What should progesterone be at 7 weeks?

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.

Is 12 low for progesterone?

Progesterone levels are usually higher when you are pregnant, but even in a non-pregnant patient, they can reach 20 ng/ml. In a pregnancy cycle, they should be greater than 10 to 12 ng/ml to have a better chance of a good pregnancy outcome.

What should progesterone levels be at 8 weeks?

Maternal serum progesterone levels rise slowly to 40 ng/mL near the end of the first trimester and then increase progressively to reach 150 ng/mL, at term. Low levels of progesterone (less than 10 ng/mL) at 6 to 8 weeks signify an abnormal intrauterine pregnancy or an ectopic pregnancy.

What level of progesterone indicates miscarriage?

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].

Does a drop in progesterone mean miscarriage?

If your progesterone levels are too low, your uterus may not be able to carry the baby to term. During pregnancy, symptoms of low progesterone include spotting and miscarriage. Low progesterone may indicate ectopic pregnancy. This can result in miscarriage or fetal death.

Why does progesterone drop in early pregnancy?

Low progesterone during early pregnancy is often the result of one of the following: An ectopic pregnancy. A miscarriage. A threatened miscarriage (when there is vaginal bleeding, spotting and/or cramping in the first trimester)

How low is too low for progesterone in early pregnancy?

During the first trimester, maternal progesterone increases slowly to around 40 ng/ml. Between the sixth and eighth weeks of pregnancy, doctors consider low progesterone levels to be less than 10 ng/ml, which is a sign of an abnormal or ectopic pregnancy.

What should my hCG levels be at 7 weeks?

Standard hCG levels

Pregnancy week Standard hCG range
5 weeks 18–7,340 mIU/mL
6 weeks 1,080–56,500 mIU/mL
7–8 weeks 7,650–229,000 mIU/mL
9–12 weeks 25,700–288,000 mIU/mL

Does progesterone drop at 6 weeks?

We have demonstrated the physiological decline in serum progesterone corresponding to a luteal-placental shift between 6 and 8 weeks of gestation with a nadir at week 7.

Can low progesterone cause miscarriage at 12 weeks?

Now with all that being said, a lack of progesterone is NOT the reason why you miscarried. The placenta takes over progesterone production at the 6th week so a luteal phase defect or lack of progesterone would not cause a miscarriage at that point.

What week does low progesterone cause miscarriage?

Women who have experienced miscarriage tend to have lower levels of progesterone, but we don’t know which causes which. Studies have shown that women who have had the corpus luteum (the gland that produces progesterone) removed before 8 weeks of pregnancy had resulting miscarriages.
