I was diagnosed with polycystic ovarian syndrome a few years back. Unlike a lot of pos sufferers my periods are long, sometimes lasting months at a time. Because of this I went to my ob-gyn 11 days ago, she put me on Provera(10mg, 1 pill for 10 days) to stop my bleeding, and then to start a normal period so that I could begin on birth control to regulate my cycle. The problem is that I never really stopped bleeding the past week and a half, so I'm unsure of when I should start on my birth control pills. Do I just start this Sunday? I think I'm having an actual period, instead of the usual bleeding, as I have PMS symptoms. My birth control pill is Loestrin24Fe, if that makes a difference.
