After going 5 months without a period and being prescribed large doses of progesterone, I finally had a period this month! My husband and I have been TTC since June of last year and I'm getting worried that I won't be able to. I have a coworker who said that she had a similar problem and ended up being infertile due to ovarian cysts. She still had periods after taking progesterone but she could never get pregnant. I'm terrified that I might have the same thing, but my OB said my ultrasound looked normal... Are my concerns valid or am I just being paranoid?
