However, it may take weeks for the level to decline to a normal (nonpregnant) value. Creinin and Vittinghoff37 reported that it took between 24 and 28 days following abortion with methotrexate/misoprostol for ß-hCG levels to decline to ≤ 10 IU/L.

The levels of hCG increase as your pregnancy progresses, peaking at around 8-11 weeks, before dropping to a lower level at 12 and 16 weeks. Some pregnancy test kits can detect hCG levels as low as 10 or 25mIU/ml. If you're pregnant, at 10 days past ovulation (DPO) you may be able to detect around 25mIU.

What Does a Low hCG Level Mean? However, falling hCG levels are not a definitive sign of miscarriage, even with bleeding. Sometimes, hCG levels drop, but then rise again and the pregnancy continues normally. Although this is not common, it can happen.

Even in women with a confirmed miscarriage, a pregnancy test may show a positive result for up to a month afterward. Depending on where you are in your pregnancy, the doctor can check your cervix, monitor your hCG levels and/or perform an ultrasound to determine whether you are miscarrying.

While hCG levels tend to fall quickly after an abortion, they can take several days or weeks to return to baseline. Usually, a home pregnancy test shows an accurate negative result 3 weeks after the end of a pregnancy. If a pregnancy test shows a positive result after 3 weeks, it may indicate a new pregnancy.

This is usually followed by another test a few days later to see how quickly the hCG levels are increasing (a sign of a healthy pregnancy). It is also possible, if your blood test came back with a very early positive, that you can get a negative test at home a few days later because of an early miscarriage.

When will you get your first period after you have a miscarriage? Many women can expect their first period four to six weeks after a miscarriage. The exact timing can vary by several weeks, however, depending on when your hCG levels return to zero.

Because today's pregnancy tests usually detect even very low levels of hCG, taking a pregnancy test in the days or immediate weeks after your miscarriage can still show a positive result. You may also continue to feel pregnancy symptoms after a miscarriage, even when it is 100 percent certain that you have miscarried.

On the other hand, slow-rising hCG levels that do not double every two or three days in early pregnancy may be a sign of problems, but can also occur in a normal pregnancy. Finally, it's important to understand that hCG levels may persist for up to a few weeks after a miscarriage.

You have residual hCG in your system after a delivery or miscarriage. After you give birth or miscarry, hCG can persist in your body for months, Dr. Williams says. The American Pregnancy Association estimates it takes four to six weeks for hCG levels to return to normal after a woman suffers a miscarriage.

What Does a Positive Pregnancy Test 12 Weeks After Miscarriage Mean? A positive pregnancy test around 12 weeks after a miscarriage is almost certainly because you are pregnant again.

If you are pregnant, your body needs time to develop detectable levels of HCG. This typically takes seven to 12 days after successful implantation of an egg. You may receive an inaccurate result if the test is taken too early in your cycle.

If you have a miscarriage, the time it takes for your levels to go to zero varies based on how high your levels were at time of miscarriage. If you miscarry very early in your pregnancy and your hCG levels haven't increased by much, your levels will usually return to zero within a few days.

If you're at risk for miscarriage or an ectopic pregnancy, you're more likely to have hCG levels that don't double. They may even decrease. Therefore, your doctor may ask you to return to their office two to three days after your baseline blood test to see if your level has doubled appropriately.

Diagnosis May Take up to a Week Even if you are having symptoms of a miscarriage, doctors often cannot confirm a miscarriage in a single day. You may need to have two blood tests two days apart to see if your hCG levels go up or down.
