A small amount of red or brown discharge but no period could be an early pregnancy symptom. This may especially be true if your cycle is as regular as clockwork but you have spotting instead of your period. It's common to have light bleeding or spotting in early pregnancy. This type of bleeding may be caused by the development of the placenta.

How do I know if it's spotting or my period?

You can usually tell the difference between pregnancy spotting and a period. Spotting in early pregnancy is much lighter than a period. Spotting shouldn't last longer than three days, and you may only notice it when you go to the loo. Most spotting is painless.

If your cycle isn't always regular though, it's possible that your period is on its way. The quickest way to be sure is to take a pregnancy test.

Pregnancy tests detect the hormone human chorionic gonadotrophin (hCG). Your levels of hCG rise quickly after the fertilised egg implants. If you get a negative result, but your period hasn't started properly, try doing another test after a few days.

I have brown discharge but no period

Again, bleeding or discharge that is much lighter in flow than your period is classed as spotting. The colour of blood may get darker as it gets older.  So a small amount of red to brown discharge but no period may well be a sign that you're in the early stages of pregnancy.

It’s also common to have some pink or brown discharge, spotting or light bleeding between week six and week seven (Hasan et al 2010, Newson 2014).

If you have bleeding that seems unusual, see your doctor to be on the safe side. Bleeding that’s lighter, and brighter, or darker red than usual, or more watery, may be symptoms of an ectopic pregnancy. An ectopic pregnancy is when the embryo implants outside the womb, and it needs immediate treatment.

Why does pregnancy spotting happen?

In the first weeks of pregnancy, your body does the job of providing your baby with nutrients and oxygen. It's thought that spotting may be triggered around the time that the placenta becomes your baby's lifeline.
There's also a possibility that it’s caused by the implantation of the fertilised egg in your womb. Or the hormones that control your periods could still be in your body.

There could be other explanations for your spotting. Your cervix could be inflamed, and bleed easily, perhaps because of an infection. If you have a positive pregnancy test, tell your midwife or doctor about the bleeding, just in case.

If you do get your period, and haven't had a pre-pregnancy visit to your GP, it's worth doing so now.

Your GP can check that you are immune to rubella, which can be harmful to unborn babies, with a blood test. They can also have a chat with you about how to get your body ready for pregnancy.

For couples trying to conceive, the missed period is often the first exciting sign of a positive pregnancy. But what should you think, then, when the pregnancy test is negative?

Causes of a Negative Pregnancy Test

There are a several possible explanations for a negative pregnancy test with a missed period that may occur in the absence of pregnancy.

Anovulation

When you are trying to conceive, it is important to determine whether you are successfully ovulating each month, as ovulatory dysfunction or anovulation may play a role in your missed period and can affect your ability to conceive.

There are many causes for ovulatory dysfunction or anovulation. Just a handful of these causes include:

  • Polycystic ovary syndrome (PCOS)
  • Thyroid dysfunction
  • Being over/underweight
  • Stress

Primary Ovarian Insufficiency (POI)

Some women may have a condition known as primary ovarian insufficiency (POI). In POI, the symptoms experienced are similar to those of menopause. As the ovarian follicle count is depleted prematurity, falling estrogen levels lead to hot flashes, vaginal dryness, and an absence of menses as the woman prematurely enters menopause.

Miscalculating Your Period

The average menstrual cycle is 28 days, but far too often we forget to note day 1 of our cycle. Additionally, cycles can sometimes vary in length from month to month. Charting Basal Body Temperature or using Ovulation Prediction Kits (OPKs) can help you get a firm grasp on your menstrual cycle to predict when you are most likely to conceive.

Second, there are a few reasons why your pregnancy test may read negative when you are, in fact, pregnant. Some reasons for this may include:

Home Pregnancy Test with a Low Sensitivity

A home pregnancy test will only detect pregnancy when the level of “pregnancy hormone,” also known as human chorionic gonadotropin (hCG), reaches a certain threshold, and it simply may not be sensitive enough to produce a positive result. Certain brands state that they can detect lower thresholds of hCG; depending on how soon you are taking the pregnancy test after the missed period, it may be worth trying again with a more sensitive brand, ensuring you are using the first morning urine for your test (hCG concentrations are highest in the first morning urine).

Taking a Home Pregnancy Test Too Soon

Another reason for a false negative pregnancy test may simply be that you took the test too early. Pregnancy tests vary in how soon they can detect hCG in your urine. It is possible that although an egg may be fertilized, your body has not started secreting enough hCG to register as positive on a test. Your body needs time for the hormone to rise to a high enough level to be detected. Most brands instruct you to wait until the first day of your missed period to test. Remember, hCG rises differently in each woman. If you suspect you are pregnant, even though the test is negative, the test should be repeated in one week.

If you are trying to conceive and your period is more than one week late with a negative pregnancy test, you should consider consultation with a fertility doctor so that you can be properly evaluated and treated, if necessary.

Can a pregnancy test be negative 2 weeks after missed period?

Take the test too early. The earlier after a missed period that you take a home pregnancy test, the harder it is for the test to detect HCG . For the most accurate results, repeat the test one week after a missed period. If you can't wait that long, ask your health care provider for a blood test.

Can I be pregnant with negative test and spotting?

If you are more than 14 days after intercourse and you are still reading negative, the bleeding might be your period. If you are not yet passed the 14-day mark and are having light bleeding or spotting, you could be pregnant and having implantation bleeding but it is too early to get a positive test result.

Can implantation bleeding occur 15 days after missed period?

Implantation bleeding happens when a fertilized egg travels down to your uterus and burrows into your uterine lining. This process is called implantation, and it can cause some mild bleeding. Implantation bleeding usually happens 10 to 14 days after conception.

Why am I 14 days late on my period and negative pregnancy test?

The most common reason for a late period and a negative pregnancy test is that your period is simply delayed and you're not pregnant. Having one or two irregular cycles a year is not unusual and does not mean there is something wrong. Reasons your period might be late include: Breastfeeding.
