Im 2 weeks late on my period. Me and my bf had unprotected sex but he did not cum inside me at all. I know about pre-cum but my boyfriend did not ejaculate since days before we had sex. I know for a fact he has peed and showered since he last ejaculated. We had sex for less than 5 mins if that matters. But this month has been really stressful, i been sleeping later than usual and my eating habits have changed. Can this delay my period? I dont feel any cramps at all and i donf feel symptoms of any kind.
