How long does spotting and cramping last in early pregnancy

During pregnancy, your body changes. A lot. And in early pregnancy, you may deal with some pretty substantial hormonal shifts. Between mood swings, exhaustion and morning sickness, you might not feel your best. But there’s another symptom that can happen in early pregnancy that you might not be thinking about — bleeding or spotting. 

“Bleeding in early pregnancy happens to 20 to 40% of women,” says Deidre Heber, DO, OB-GYN at Geisinger. “Most of the time, it’s nothing to worry about.”

Potential causes of first trimester bleeding 

Bleeding during the first trimester can look different for everyone. The amount can range from light to heavy. For some, it can be intermittent. Others may have more constant bleeding or spotting. And it may or may not be painful. 

Here are a few things that might be behind it.

Implantation bleeding

Early in pregnancy (sometimes before you know you’re pregnant), you may have some spotting when your period is due. This common occurrence is called implantation bleeding. “It happens between 6 and 12 days after conception as the fertilized egg implants into your uterus,” Dr. Heber says. This bleeding is typically light and may last for a few days.

Cervical changes

During pregnancy, there’s increased blood flow to your cervix. Having sex or getting a Pap smear, which cause contact with the cervix, can trigger light bleeding. Other cervical changes that can trigger bleeding include: 

  • Polyps
  • Minor infections
  • Cervical ectropion (when cells from the inside of the cervix move to the outside)

Hormones

In the early weeks of pregnancy, your body starts making the hormones you need to sustain a pregnancy. This change can cause your progestin levels to drop. That drop may lead to spotting or light bleeding.

Miscarriage

Since miscarriages are most common during the first trimester, worrying about bleeding is normal. Light bleeding or spotting doesn’t automatically mean you’re miscarrying. But if your bleeding is heavy, bright red or you’re passing clots and in pain, contact your healthcare provider. They can explain next steps.

Most women who miscarry go on to have healthy pregnancies. But having a miscarriage is a loss that families may need help handling. Don’t rush the grieving process, and find a support group or counselor if you feel you need it.

Ectopic pregnancy

An ectopic pregnancy happens when a fertilized egg implants outside the uterus, like in your fallopian tube. When that happens, it can lead to heavy bleeding, pain and other serious symptoms. “An ectopic pregnancy is an emergency,” says Dr. Heber. “If you have symptoms, contact your provider immediately.”

When to call the doctor about bleeding

Call 911 or go to the nearest emergency room if you have any of these symptoms:

  • Severe pain or cramps low in the abdomen
  • Severe bleeding, soaking greater than one heavy pad per hour, with or without pain
  • Passage of blood clots or tissue
  • Dizziness or fainting
  • Chills
  • Fever higher than 100.4° F

If you’re pregnant and bleeding heavily, don’t use a tampon. Wear a pad instead. “Doctors need to know how much you’re bleeding to gauge the severity,” says Dr. Heber.

And if you’re passing tissue, consider bringing it in for testing.

Your doctor may use an ultrasound to determine the cause of your bleeding. Once they find the cause, they’ll work with you on a treatment plan.

Healthy parent, healthy baby

Building good habits now can help you have the healthiest pregnancy possible. Dr. Heber makes these suggestions to help you (and your baby) feel your best.

  • Eat a nutritious, well-balanced diet
  • Exercise regularly
  • Avoid alcohol, recreational drugs and cigarettes
  • Reduce caffeine intake to 1-2 cups a day
  • Attend regular prenatal visits
  • Take your prenatal vitamins

Introduction

This leaflet has been produced to give you general information about your condition.  Most of your questions should be answered by this leaflet.  It is not intended to replace the discussion between you and your nurse/doctor, but may act as a starting point for discussion.   If after reading it you have any concerns or require further explanation, please discuss this with a member of the healthcare team .

What is vaginal bleeding in early pregnancy?

Vaginal bleeding is common in early pregnancy and does not always mean there is a problem. However, bleeding can be a warning sign of a miscarriage.

What are the causes of early bleeding?

There are a number of causes of bleeding in early pregnancy which include:

Spotting or bleeding may occur shortly after conception, this is known as an implantation bleed. It is caused by the fertilised egg embedding itself in the lining of the womb. This bleeding is often mistaken for a period, and it may occur around the time your period is due.

Hormonal bleeding is when some women experience a light bleed at around four to eight weeks of pregnancy, or around the time their period would have been due. This can be very confusing for women who are pregnant and is the reason many women do not realise they are pregnant for a while. Again, it is totally normal. This usually settles around the 13th week of pregnancy as by this time the placenta is sufficiently developed to produce all of the hormones needed to sustain the pregnancy.

After the egg is fertilised, the fertilised egg then goes on to implant itself into the lining of the womb (uterus). Sometimes this results in a little bleeding that shows up on an early scan as a haematoma(collection of blood). This is not anything to worry about. When it happens the woman may notice a small amount of vaginal bleeding, but this is not necessarily the case.

The haematoma will gradually disappear and in most cases, the pregnancy remains safe.

Cervical Erosion (alternatively known as cervical ectropion) may be a source of spotting or bleeding. The blood supply to the womb and cervix is increased during pregnancy and the cervix may bleed harmlessly and painlessly. An erosion may cause bleeding following sexual intercourse; therefore this type of bleeding must always be reported to your doctor.

Can bleeding indicate a miscarriage?

Not all bleeding in pregnancy is harmless, and it can be the first sign of a miscarriage. As many as 1 in 5 pregnancies are thought to end in miscarriage. The cause of miscarriage is not always known, but researchers have shown that in some cases there is a problem with the developing pregnancy, which means it is unable to develop normally. For most women, miscarriage is a very sad and upsetting experience.

Experiences of miscarriage vary. In some cases there may be only very slight spotting, in other cases bleeding may stop and start or heavier bleeding with clots and cramping period type pains can occur. Sometimes there may be no bleeding at all.

For further information relating to miscarriage, please ask your nurse for further details.

What should I do if I experience bleeding during pregnancy?

If you experience bleeding, it is wise to have this checked out. If you have been seen in the Early Pregnancy Assessment Unit (EPAU) during your pregnancy, you may contact us directly, up to 15 weeks + 6 days of pregnancy. Your GP or midwife can also help you.

If you have been seen in the EPAU and you then experience more bleeding contact the EPAU. Depending on how much bleeding and for how long the nursing staff will decide if you need to be seen again. A rescan is not always necessary. Sometimes the nurse will advise that you monitor this bleeding at home.  A rescan will only be performed if bleeding heavy with clots. If there is a significant change in your symptoms then the nurse will make an appointment to come to EPAU and be either rescanned or to be assessed by the doctor. If bleeding unmanageable then the nurse may advise to be assessed on ward 30 or the Emergency department depending on your symptoms.

What if I experience pain in early pregnancy?

If you experience pain that does not go away, or which you feel is becoming more sever, you should seek advice from your doctor, nurse or midwife. It is important that any serious causes of pain are excluded. For example there is a need to rule out an ectopic pregnancy (this is where the pregnancy develops outside the womb).

What kind of pain may I feel?

Some women experience abdominal (tummy) pain in early pregnancy. This may be low cramping pain, similar to that felt during a period, or a stitch like or stabbing pain on one or both sides of the tummy. Aches and pains may come and go or be present continuously.

What are the causes of abdominal and back pain?

Some of the aches and pains experienced during pregnancy are thought to be due to hormonal changes. Large amounts of the hormone progesterone are produced, which are needed to sustain pregnancy. In addition to this, progesterone acts on the muscles, ligaments and joints causing them to become slacker and more flexible. This hormonal effect is thought to be responsible for some of the stitch like pains that some women experience in the lower part of the tummy and in some cases this can be quite severe. The same hormones can be responsible for constipation during pregnancy; this can also cause abdominal pain.

The enlarging womb is made up of layers of muscles and is held in place in the pelvis by supporting ligaments. As the womb expands to accommodate the developing baby, it can pull on the ligaments and muscles, to cause these “growing pains”.

The backache that some women get in early pregnancy is also thought to be due to a hormonal effect, and the supporting muscles are softer.

Abdominal and/or backache can also be a sign of a urine infection. This may also cause burning or stinging when passing urine and the need to pass urine more frequently. You must inform your doctor of these symptoms, so that a urine test can be obtained and treatment given if needed.

Pain on its own does not mean that a miscarriage will occur. However if you experience bleeding as well as pain this could indicate a threatened miscarriage and you should always seek advice from your doctor, nurse or midwife.

Can I take pain relief medication during pregnancy?

If you find that you need to take pain relief medication to relieve any pain, it is safest to use something simple such as paracetamol. Drugs such as aspirin and ibuprofen should be avoided. If you find that you need a stronger pain relief medication, you must always check with your doctor, nurse or midwife first.

Scanning in early pregnancy

An ultrasound scan is used during pregnancy for a number of reasons. In the first three months of pregnancy it can be used to check the presence of the baby’s heartbeat, which can be reassuring if you have experienced a problem, such as vaginal bleeding or pain. A scan will also be used to check to see if the pregnancy is in the correct place and to accurately predict the estimated date of delivery (the date the baby is due) by measuring the end points (size) of the embryo or fetus.

Will I have an ultrasound scan?

Yes, if the nurse/doctor thinks it is appropriate for you to have a scan.

What is an ultrasound scan?

Ultrasound uses high frequency sound waves that are sent out from a transducer or probe. These sound waves are received back and converted into an image on a screen.

Is it safe to have a scan in early pregnancy?

Yes it is safe, there is so far no evidence to suggest that an ultrasound scan is unsafe.

What type of scan will I have?

A vaginal scan is the best method in early pregnancy (under 8 weeks) as it gives us a more accurate result at an earlier stage in pregnancy than an abdominal scan. It may be a little uncomfortable but it is safe to be done, you do not need a full bladder when having a vaginal scan. If you have concerns about a vaginal scan, please let the nurse, midwife doctor know.

What will the scan tell us?

A scan can only tell us how your pregnancy is at that particular time. Unfortunately it is no guarantee that your pregnancy will continue successfully. If your symptoms persist or become worse, you must contact EPAU, midwife or your GP.

In later pregnancy ultrasound scanning is used to look more closely at the anatomy and organs of the developing baby. This is usually done between 18 – 21 weeks.

What if the scan confirms a miscarriage?

If the scan confirms that you have miscarried, the choices of how we can manage this will be discussed with you.

Occasionally, the scan may pick up an unexpected finding such as a cyst on the ovary. If this is the case, the staff will explain the findings and any necessary follow up.

Common abbreviations used on scans

LMP – Last menstrual period.

FH – Fetal heart-rate.

EDD – Estimated date of delivery.

FM – Fetal movement.

USS – Ultrasound scan.

YS – Yolk sac.

CRL – Crown to rump length (a measurement of the embryo/fetus used in early pregnancy).

BPD – Bi-Parietal Diameter.

HC – Head circumference. Both of these measurements of the fetus are used in later pregnancy, after 12-14 weeks.

How long does spotting and cramping last in early pregnancy

How long does cramping and bleeding last in early pregnancy?

This is called implantation bleeding and it happens around 6 to 12 days after conception as the fertilized egg implants itself in your womb. This bleeding should be light — perhaps lasting for a couple of days, but it's perfectly normal.

Is it normal to bleed and have cramps during early pregnancy?

Bleeding and pain in early pregnancy is common. Heavy bleeding or blood clots could indicate a miscarriage or an ectopic pregnancy. Such symptoms can include bleeding, spotting, cramps and stomach pain.

How much spotting is normal during early pregnancy?

About 20% of women have some bleeding during the first 12 weeks of pregnancy. Possible causes of first trimester bleeding include: Implantation bleeding. You may experience some normal spotting within the first six to 12 days after you conceive as the fertilized egg implants itself in the lining of the uterus.

How long does pregnancy implantation cramps last?

The duration of implantation cramps varies from person to person but doesn't last longer than a few days. Some people experience a few minor twinges over a few hours or the course of a day. On the other end of the spectrum, some experience intermittent cramping that comes and goes over one to three days.
