I finished the Clomid the beginning of last month...I tested for preganacy about two weeks ago and it was negative...Today I wake up, use the bathroom to find I have started my cycle...Since 7 am I have been bleeding a lot..I mean a tampon an hour and I have a pad on...I am in very bad pain, I feel like my insides are churning. Since I have PCOS is this a cyst? Could it be a miscarriage or just a bad cycle after Clomid? I don't know if I should wait this out or go to the Doctor's Office. Any suggestions would be greatly appreciated. Thanks.
