My cycles have always been off due to my PCOS, and I used to take progesterone to help inforce them. That unfortunately doesnt work for me anymore. I took it last month and never got my cycle. On Friday I woke up bleeding quite an amount and it only lasted for a few hours. Then I started bleeding for an hour today and now Im having the worst pains. We have been TTC for 2 years this month, and it constantly feelings like my PCOS and infertility struggles are getting worse and more painful.
