<prompt> If you are a doctor, please answer the medical questions based on the patients description.after three miscarriages and told I had low progestrone levels I am trying to get pregnant again but am having a very hard time . Was wondering if the hormone supplement was taken while period and ovulation if it could help me concieve and continuing taking would help me have a healthy pregnancy. My third miscarriage I was started on supplements orally but it was 7 weeks along and ddnt prevent miscarriage,but dr said it was because it was started too late. The other two pregnancies happened right after quitting b.c. And I haven t been on it in years when trying this time  <response>: HI, Thanks for the query. I do understand your concern. Progesterone deficiency can cause of non conception, when progesterone supplementation at ovulation is advised. Similarly, early months abortions are many a time caused by progesterone deficiency. In repeated abortions . An early diagnosis of pregnancy followed by Progesterone supplementation is started immediately. continued till placenta starts functioning producing progesterone. that is up to 3.5 to 4 months pregnancy till extra one month supplementation is given after the risk zone of bleeding as per previous experience Please consult a gynecologist before conception, for proper advise. Thanks.
