Chemical pregnancy facts

A chemical pregnancy is an early pregnancy loss that occurs shortly after implantation. Chemical pregnancies may account for 50 to 75 percent of all miscarriages.

Chemical pregnancies take place before ultrasounds can detect a fetus, but not too early for a pregnancy test to detect levels of hCG, or human chorionic gonadotropin. This is a pregnancy hormone the embryo creates after implantation. Your doctor can confirm a chemical pregnancy by testing your blood for it.

Experiencing a miscarriage just one or two weeks after a positive pregnancy test can be devastating.

A chemical pregnancy can have no symptoms. Some women have an early miscarriage without realizing they were pregnant.

For women who do have symptoms, these may include menstrual-like stomach cramping and vaginal bleeding within days of getting a positive pregnancy result.

It’s important to note that bleeding after a positive pregnancy test doesn’t always mean a chemical pregnancy. Bleeding is also common during implantation, which is when the embryo attaches to the uterus. This process can rupture or damage tiny blood vessels along the uterine lining, resulting in the release of blood. Spotting often appears as a pinkish or brownish discharge. This is normal 10 to 14 days after conception.

A chemical pregnancy doesn’t usually last long enough to cause pregnancy-related symptoms like nausea and fatigue.

This type of miscarriage differs from other miscarriages. Miscarriages can occur at any time during a pregnancy. But they are more common before the 20th week. A chemical pregnancy, on the other hand, always occurs shortly after implantation. Since most often the only symptom is menstrual-like cramping and bleeding, some women assume they’re having their menstrual cycle.

A chemical pregnancy can also happen after in vitro fertilization (IVF). An egg is removed from your ovaries and mixed with sperm. The embryo is transferred to the uterus after fertilization.

IVF is an option if you can’t conceive because of:

  • damaged fallopian tubes
  • ovulation problems
  • endometriosis
  • uterine fibroids
  • other fertility issues

A blood test is usually given within 9 to 14 days after IVF to check for a pregnancy, depending on the clinic you use.

Blood test results will be positive if implantation took place. But sadly, abnormalities with the embryo may cause a chemical pregnancy shortly thereafter.

A miscarriage after IVF can be heartbreaking, but it’s also a sign that you can get pregnant. Other attempts at IVF may be successful.

The exact cause of a chemical pregnancy is unknown. But in most cases the miscarriage is due to problems with the embryo, possibly caused by a low quality of sperm or egg.

Other causes may include:

  • abnormal hormone levels
  • uterine abnormalities
  • implantation outside the uterus
  • infections like chlamydia or syphilis

Being over the age of 35 increases the risk of a chemical pregnancy, as does certain medical problems. These include blood clotting and thyroid disorders.

Unfortunately, there are no known ways to prevent a chemical pregnancy.

A chemical pregnancy doesn’t always mean you’re unable to conceive and have a healthy delivery. While there’s no specific treatment for this type of miscarriage, there are options to help you conceive.

If you’ve had more than one chemical pregnancy, your doctor can run tests to diagnose possible underlying causes. If your doctor can treat the cause, this can reduce the risk of another chemical pregnancy.

For example, if an early miscarriage was caused by an undiagnosed infection, taking antibiotics to clear the infection can improve your chances of conceiving and having a healthy delivery in the future. If the miscarriage was due to problems with your uterus, you may need a surgical procedure to correct the issue and have a healthy pregnancy.

You should also know that a chemical pregnancy isn’t the only condition that causes the body to produce the pregnancy hormone. Higher levels of hCG can also occur with an ectopic pregnancy. This is when an egg implants outside the uterus. Since an ectopic pregnancy can mimic a chemical pregnancy, your doctor may run tests to rule out this condition.

A chemical pregnancy doesn’t mean your body is unable to have a healthy pregnancy. If you learn the reasons for an early pregnancy miscarriage, you may be able to receive proper treatment. This can correct the underlying cause.

Speak with your doctor and discuss your options. Your doctor can also provide information on support groups or counseling services. These can be critical if you need emotional support after a miscarriage.

Does a negative pregnancy test mean miscarriage is complete?

The only time a home pregnancy test result can suggest miscarriage is if you have a pregnancy test show a negative result after having taken a previous pregnancy test that was positive. This can be a sign of a chemical pregnancy—a very early miscarriage.

How long after a miscarriage will a blood pregnancy test be negative?

It typically takes from one to nine weeks for hCG levels to return to zero following a miscarriage (or delivery). 1 Once levels zero out, this indicates that the body has readjusted to its pre-pregnancy state—and is likely primed for conception to occur again.

Can you have a period after miscarriage with hCG still in system?

Many women can expect their first period four to six weeks after a miscarriage. The exact timing may vary by several weeks, however, depending on when your hCG levels return to zero. Your body will still think it's pregnant until this hormone is gone.

When should I repeat a pregnancy test after miscarriage?

If the pain and bleeding have lessened or stopped completely during this time, this usually means the miscarriage has finished. You should be advised to take a home pregnancy test after 3 weeks. If the test shows you're still pregnant, you may need to have further tests.
