what causes low progesterone levels and what can we do to make them higher to get pregnant?

Hi, Progesterone usually increases prior to a womans period and cause the period to arrive in some cases. Low progesterone may cause spotting but so does pregnancy.

In unfertilized ovum mainly progesterone (high quality) and low quantity of estrogen is released from the corpus leuteum (remaining part of the roptured follicle in ovary. This increased progesterone prepares the uterus for pregnancy.

If fertilization occur progesterone estrogen and hCG are released.

When estrogen and progesterone levels are low, shedding of the endometrial layer (menstruation) occurs.

Progesterone can be low for two different reasons. It can be predicting a failing pregnancy, or it can just be that your body is having a hard time producing it and you need a hormone supplement. 1.5 is a very low progesterone level. Most doctors like you to be no lower than 10. If you are bleeding or have any other miscarriage symptoms along with it, I am sorry to say, you may be miscarrying. Hopefully you are not, and the doctors can get you on a prescription ASAP.

The best of luck to you! In the future, you can always have the doctor check your progesterone levels at a non-pregnancy time to rule out if you have a progesterone imbalance, or if your levels were just low because of a failing pregnancy.
