From experience, you don't need a period to ovulate . I think it would be a good investment to purchase ovulation predictor kits to keep track of your ovulation or lack there of.
You don't have to have a period to ovulate regularly. I would ask for a hormone blood work throughout a cycle to see when you are ovulating. I would also seek another Dr.
Going to give that a try. Staying positive in hopes of a positive. Wish me luck!
Try Medroxyprogesterone it is used to treat absent, irregular, and heavy periods.
