Time Frame for hCG to Return to Normal It can take around a week to return to zero with a chemical pregnancy (a very early pregnancy loss) and up to a month, or even more, with a miscarriage that occurs later in pregnancy. After that, a pregnancy test won’t be positive.

Gabapentin and pregabalin have a minimal risk of causing false-positives and are other options that could be used. Trazodone is an antidepressant frequently used as a sleep aid.

A chemical pregnancy can only be detected through a pregnancy test, which shows elevated hormone levels. A pregnancy becomes clinical when a doctor can verify the pregnancy through an ultrasound or fetal heartbeat. A chemical pregnancy has no signs that can be felt or heard.

Even if you did miss your period but it hasn’t been at least a couple of weeks since you conceived, you could still get a “false negative.” That’s because you need a certain level of a hormone called HCG (human chorionic gonadotropin) in your urine for the test to work.

In general, bleeding associated with an impending miscarriage or chemical pregnancy (a nonviable pregnancy) may begin as spotting and then turn into a heavier flow with visible clots and a dark red color, similar to a heavy menstrual period.

Chemical pregnancies make up anywhere from 50-75% of all miscarriages, but they are not an indication that you can’t get pregnant. In fact, many doctors look at chemical pregnancies as good signs that you can get pregnant, and probably will in the future.

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.

At around 8 to 11 days after conception, your blood still has low levels of hCG. After this, hCG levels should double every 2 to 3 days for the first 6 weeks of your pregnancy. Levels of this hormone peak around the end of your first trimester and then go down over the rest of a pregnancy.

A chemical pregnancy is a very early pregnancy loss. It happens before the fifth week of pregnancy, usually about a week after your menstrual period is due. Chemical pregnancies are very common, and they often happen before a woman even realizes that she’s pregnant.

In fact, a woman may ovulate and get pregnant as soon as two weeks after experiencing a chemical pregnancy.

HCG levels in pregnancy HCG levels higher than 5 million international units per milliliter (mIU/mL) typically indicate pregnancy. Your first test result is considered a baseline level. This level can range from very small amounts of hCG (such as 20 mIU/mL or even lower) to larger amounts (such as 2,500 mIU/mL).

In some cases, the fetus dies but the womb does not empty, and a woman will experience no bleeding. Some doctors refer to this type of pregnancy loss as a missed miscarriage. The loss may go unnoticed for many weeks, and some women do not seek treatment.

A chemical pregnancy does not produce an embryo Technically, you’ve conceived, which is why a pregnancy test might give you a positive result. But if no sign of an embryo appears on a second ultrasound at a later date, then you probably experienced a chemical pregnancy, Cackovic tells Insider.
