by taking the morning after pill effect your period cycle, by making i irregular? and my girlfriend and i had sex last week and i used a condom and i was going really slow, we went for about 5-10 minutes beacuse we were tired from the long day, the thing is i wasnt even close to cumming, so we stopped. i checked the condom, it didnt break, it didnt have any holes, it was fine. but now she is 2 weeks late from her period. is she pregnant? or is her cycle messed up from taking the morning after pill a one before all this, also we did travel to spring break, but did not have sex does this effect the cycle?
