My periods are always irregular (months without one and such). I was just given orthocyclen by my doctor today and she didn't mention waiting for my period before starting my first pack. She just said to have back up birth control for two weeks and said if i wanted i could wait until Sunday to start. Since I'm not sure if I'll get my period, should I go ahead and start the pill? I've had a normal period for two months without the pill but I'm not sure if I'll have a normal one this time. I'm fine with using other birth control so that's no issue for me.
