Is it okay not to have your period the day after sex?
Well...your title asks one question and your question asks the opposite so I'll try to answer both...
If your period is due then it's fine to get it the day after sex...if your period is due a couple of days to a week later it's normal to get it right after sex.
If your period is not due then it's fine to not get it the day after sex...If your period is due the day after you have sex sometimes it's normal for it to be delayed.
If you had unprotected sex then there is always a chance of pregnancy...no matter when you're supposed to get your period, but since it takes awhile for a fertilized egg to implant in your uterus you could still get your period the day after sex.
I dont know what to do.. I had unprotected sex and then I had my period right after and he says he did not cum or pre-cum. does this still mean im pregnant. By the way I'm 13. and SCARED ): Help please??
