So I've been TTC for a year now and I did not ovulate last month. My fertility doctor put me on prometrium to start my period. Well i have been having light bleeding for the last three days and the doctor says that I can't considerate a period until heavy flow happens. I can't start my ovulation drugs until I start my period...idk what to think, I just don't want to miss my chance this month because if I don't take the ovulation drugs at the right time it will mess this month up. Do any of you have experience with having light bleeding for awhile while on prometrium And then get your full flow period?
