Yesterday I miscarried for the 2nd time in 6 months. My doctor is suggesting multiple tests to check my uterus, hormones, etc...I am most curious about what Progestrone supplements entail. I have had problems with cysts since I was 16 (10 years) and I am wondering if that could mean that my hormones are to blame. Can you please let me know if there could be a link between my cysts and the miscarriages? Also, can you please let me know what progesterone supplements entail and how they are administered?
