4 Weeks After Miscarriage Positive Pregnancy Tests

Can a Pregnancy Test Show a Positive Result After a Miscarriage?

Even though it may seem unlikely, a positive pregnancy test can occur after a miscarriage. However, in almost all cases, this is a false-positive result.

Common Causes of False-Positive Test After Pregnancy Loss

Here are some typical reasons for a false-positive test following a miscarriage.

The placenta continuously produces hCG during pregnancy, which is in charge of preserving the fetus’s early development. Miscarriages are typically unexpected, so the shock to the system takes some time to reset. hCG may still be produced during this time, which could lead to a positive pregnancy test.

In some cases, miscarriages may be incomplete. That is to say, the uterus may still contain a piece of the ovum. This scenario may also lead to a false-positive result. 8 weeks after a miscarriage, a positive pregnancy test indicates that the pregnancy was not complete.

A false positive on the pregnancy test may be caused by a rare condition called molar disease or molar pregnancy. There are two types of this condition, which is a type of gestational trophoblastic disease. A complete molar pregnancy lacks an embryo or healthy placental tissue. The embryo and healthy placental tissue are present in a partial molar pregnancy, but the embryo is abnormal and malformed. Molar pregnancies have risky side effects, such as cancer, and demand immediate medical attention.

How long will a pregnancy test be positive after a miscarriage?

Depending on how far along you were in your pregnancy and the type of pregnancy you had, it will take a certain amount of time for your hCG level to gradually return to normal. Levels may continue even after a miscarriage, but they usually begin to decline and return to their baseline or pre-pregnancy levels after about six weeks. If your pregnancy ended abruptly, you most likely have low levels of hCG, whereas if it continued for a longer period of time, you have higher levels in your bloodstream.

Your hCG levels were lower and will likely return to baseline faster if the pregnancy ended early or soon after implantation. Even though the hormone was being produced at a rate high enough to show up on a pregnancy test, without a successful implantation, its levels will drop quickly. After an early miscarriage, it might only take a few days for your hCG levels to return to normal.

At the start of a pregnancy, your hCG levels double every two to three days, peaking around week ten. If you have a miscarriage later in pregnancy, you will naturally have more hCG in your blood and it may take longer for levels to return to their pre-pregnancy baseline.

After a miscarriage, many medical professionals typically advise waiting several months before trying to get pregnant again. There is no medical reason to wait this long, but every situation is unique and will depend on a variety of factors, including your personal medical history.

Waiting until your body and mind are both prepared for miscarriage is important because it can be physically and emotionally taxing. Physically, your body is capable of becoming pregnant once hCG levels return to those from before the pregnancy and ovulation has resumed. Although recent studies have refuted the need for a prolonged waiting period, it’s still crucial to give your body time to heal and for your pregnancy hormones to return to normal.

The need to wait before trying to conceive once more is due to the need to give your body time to heal.

It gives you time to process the events on an emotional level and gives your body a chance to get back to its best state to support a future pregnancy.
