What is a chemical pregnancy and what causes it?

A chemical pregnancy is a term used to describe a very early miscarriage which occurs before the fifth week of gestation and well before the fetus can be visibly detected on an ultrasound. A chemical pregnancy is believed to affect as many as 75 percent of pregnancies that end in miscarriage.

Similarly, you may ask, can hCG levels indicate miscarriage?

In general, however, if the hCG levels are dropping in the first trimester, this probably is a sign of impending miscarriage. 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.

What hCG is considered pregnant?

An hCG level of less than 5 mIU/mL is considered negative for pregnancy, and anything above 25 mIU/mL is considered positive for pregnancy. The hCG hormone is measured in milli-international units per milliliter (mIU/mL).

What are good progesterone levels in early pregnancy?

They can range from 9-47ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy. With both hCG levels and progesterone levels, it is not the single value that can predict a healthy pregnancy outcome.
