What causes your period to stop hcg or progesterone?

Elevated levels of progesterone is what causes your period to stop, but hcg plays a role in that too, as it is the presence of hcg (from implanted embryo) that tells the corpus luteum to keep pumping out the progesterone after the normal luteal phase length. If there is no hcg detected the corpus luteum tapers down progesterone production after about 14 days and the endiometrial lining starts to break down when the progesterone no longer is present to support it.


If the doctor took your blood to check progesterone levels what does that mean?

Progesterone is not pregnancy related. It is a hormone that increases in your blood prior and during your period. It means he is checking to see if you have ovulated that cycle. High progesterone levels indicate that you have ovulated. http://thefertilityshop.com
