I have not been sexually active for over the past year until this one recent time. We had sex and he used a condom (which did not break). Since I am paranoid about these kind of things, I made sure that he pulled out way before he finished. And so he did. However, my period is very late. I do not know why? I went of the pill thi past month and have no gotten a period sans birth control yet. Also, I have been under an enormous amount of stress lately. I am making myself worried over nothing?

I am currently in school studiny these types of things but what i know is that the mind is a powerful thing. Think about it, i mean have you ever read something that had side effects, and you start to notice things happening with you like... Headache when it said headaches, you feel a little hot when it says you could have a fever. I mean i think overall you should go to the doctor but just remember a lot of things can play a vital role with your body. Stress is the number 1 factor for me and i had irregular periods for sometime, so just try to relax and things will fall into place. Hoped this helped.

Stress is probably the reason why you haven't had your period. I can tell you from experience. Just relax. Take a day for yourself. Go shopping or take a long bath. Maybe put soft music. Maybe read a book or watch a movie. Pamper yourself for a day. And don't think about it. When you least expect it you will get your period. If you are still worried you can always try a home pregnancy test. Best of luck.
