During the first trimester, maternal progesterone increases slowly, to around 40 ng/ml. Between weeks 6–8, doctors consider low progesterone levels to be less than 10 ng/ml, which is a sign of an abnormal or ectopic pregnancy. A level that falls significantly below normal (below 5 ng/ml in the first few weeks of pregnancy, for instance) is considered low progesterone, but luckily, most women have normal levels of progesterone, and low progesterone during pregnancy is quite uncommon.
