My last menstrual period was on feb 13 and I had unprotected sex 3 days after my period ended. The guy never came in me neither out of me. No semen around. On the next day less than 24 hours of having sex, I took plan B. now it is march the 2nd and I have not get my period. I have never been regular but I still took two pregnancy tests and hey were both negative. I am just super stressed and worried. Even though I have always been late on my periods. Does any one has any advices or maybe over the counter meds to induce my period to just feel free of stress alredy?

1. there is no such thing as "pull out" there is lots and lots of sperm in the early fluids, so he does not have to reach climax and discharge to make you pregnant. There are plenty of sperm long before that point.

2. plan B of course is not 100 percent effective.

Now of course plan B can effect your cycle so that is most likely the problem, but if you are going to be sexual active get on a birth control, make him use condoms also and study birth control so you know the facts better.

Thank you, I am a nursing student and I know all aout birth control, but really this one night I was stupid enough to do it just like that.. I am so stressed.
