When you pop your cherry do you miss your period?

No.

Your period can be delayed due to many factors. The chemistry of your body has changed, stress and the fact that you probably lost some blood already. Mine was delayed for a few weeks and I was not pregnant. Taking a pregnancy test eliminates other factors as well. If you had sex during your "infertile time" (week or so before your period starts; "dry time") you probably need not worry, but pregnancy at this time is not completely impossible either.
