periods

I've been off of the pill since June. I've been irregular. I just moved and now I'm not getting my period. My last period was for 2 days in September. I'm not pregnant either. I now have birth control pills to take. When should I take them and will it make a difference?...

For the past few months my period hasn't been normal. I'll go weeks or sometimes a whole month without it. I am currently in a relatively new relationship (about 2 months now) and we've had sex a few times, but he pulls out right before. I know about the risk of pre-ejaculate and such, but how possible is it to get pregnant from it?...

I lost my right ovary in March from an having an ovarian tumor, I am currently on the pill and my boyfriend uses condoms. However sometimes we fool around a little before he puts a condom on. My question is...what are the odds that I could still get pregnant considering my situation? What if he pre-ejaculates beforehand and doesn't tell me?...

I am 20, in India, and my periods are irregular: I have Polycystic Ovary Syndrome. I've never had sex in my life, not even a thought of doing so before marriage. Somewhere around the the 18th of May, we were alone and talking together and God knows how, my boyfriend and I just indulged in heavy kissing on bed with clothes on for say 3-4 minutes....
