If only progesterone can suppress ovulation, why do most birth control pills have both E and P? I know there are BC's than only contain a progestin, like the depo shot, but then why do combo BC's even exist? I know this doesn't sound like it has anything to do with BE, but I feel like I'm missing a key piece of info.
Hmmm. I have experienced the opposite with pc/ Pm. I can stop my mense cycle with PM and bring it on with PC. Not much experience w/ BC but I am wondering why this is for some and not others.
