So on Tuesday (2/19/13) I had unprotected sex with my boyfriend for like 1 minute. He did NOT ejaculate in me but of course there's always pre- which I don't know contains sperm or not. It's now Wednesday (2/27/13) and my last period started on Jan 27 and I have a 7 day period. I have not had any sort of bleeding whatsoever. Someone pleeeease help me. I don't know if it's the stress of thinkng I'm pregnant, actually being pregnant, or my period just switching around AGAIN, but people I cannot get pregnant right now! I've told my boyfriend we cannot have unprotected sex anymore and he understands. Please help me anyone!

You need to wait until your period is two weeks late, then test with the first urine of the morning. Remember that no birth control is 100% effective, so if you don't want to become pregnant, don't have sex.
