2 to 25 ng/mL in the luteal stage of the menstrual cycle. 10 to 44 ng/mL during the first trimester of pregnancy. 19.5 to 82.5 ng/mL during the second trimester of pregnancy. 65 to 290 ng/mL during the third trimester of pregnancy. fertilityeggspurt.comИзображение:fertilityeggspurt.comNormal levels of progesterone during pregnancy are as follows: In early pregnancy normal levels of progesterone are: 1 – 28 ng/ml (3.18 – 89 nmol/L) During the first trimester normal progesterone levels are: 9 – 47 ng/ml (28.5 – 149 nmol/L) The hormone progesterone is secreted during early pregnancy and prepares the uterus for pregnancy. It causes the luteal phase to start and transforms the endometrium (uterine lining) by thickening it to receive an embryo. The embryo is the result of the female’s egg when it’s fertilized by the male’s sperm.

What is considered low progesterone in early pregnancy?
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.
What level of progesterone indicates pregnancy?
Pregnancy 1st trimester: 11.2 to 90.0 ng/mL or 35.62 to 286.20 nmol/L. Pregnancy 2nd trimester: 25.6 to 89.4 ng/mL or 81.41 to 284.29 nmol/L. Pregnancy 3rd trimester: 48 to 150 to 300 or more ng/mL or 152.64 to 477 to 954 or more nmol/L.
At what progesterone level will you miscarry?
Many studies have shown that low serum progesterone is associated with threatened miscarriage. Our group has validated a single serum progesterone cutoff of 35 nmol/L taken at presentation with a threatened miscarriage can differentiate women at high or low risk of subsequent miscarriage [14, 15].
What should progesterone levels be at 4 weeks pregnant?
Progesterone levels also can have quite a variance at this stage of 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.
What is the normal range of progesterone levels during pregnancy?
Studies show that progesterone levels of less than 35 nmol/L (11 ng/ml) indicate a high risk of miscarriage before week 16 of pregnancy. ( study ) According to the American Pregnancy Association, “They (progesterone levels) can range from 9-47 ng/ml in the first trimester, with an average of 12-20ng/ml in the first 5-6 weeks of pregnancy.”
What is the role of progesterone in early pregnancy?
The purpose of this hormone in the early stages of pregnancy is further stimulation of your ovaries to produce more estrogen and progesterone to support your pregnancy. In early pregnancy, progesterone levels increase with the gestational growth and age of your fetus. Progesterone levels vary during your menstrual cycle.
What is a low progesterone level at 6 weeks pregnant?
Current research suggests that progesterone levels lower than 6-10ng/ml by the 6th week of gestational indicates an unviable pregnancy. Those that are worried about low progesterone levels can request a blood test from their doctor. Results are usually available within one day.
How much progesterone does your body produce during the first two weeks?
During the first two weeks, your body will still produce progesterone from the ovaries at about 1-1.5ng/ml. Regardless of the fact that you are not in pregnancy yet, your pregnancy life is measured from the first day of your last menstrual period because your body will already be preparing forpregnancy.
