I had unprotected sex 08/30 around 11:00pm-ish. I took Plan B on tuesday Sept 02, at 1:30pm. Well, started what I think may be my menstrual cycle yesterday but now I am a little anxious and dont even remember the dates that my menstrual cycle 'usually' falls on...
There is no data on things like that. I've never known anyone that continued having periods when pregnant. You are doing two foolish things. You are having unprotected sex and you don't even know when your period is due. Get on birth control so you don't have these worries. Plan B has side effects of weird bleeding and delayed periods. Plan B is meant for emergencies not routine birth control. It has a failure rate of 5-15%. That is why its not for regular birth control. It also screws up your cycle. You took it fairly early so it would work better.
