Re: just curious?
It depends on when you ovulate. Usually, the 14 days before your period and the 14 days after is when you're most at risk of getting pregnant. That's not fail proof though. Urine pregnancy tests usually pick up a pregnancy 5-7 days after your period. A blood test for pregnancy is %100 fool proof. It's best not to worry until you don't get your period. If it's due next week, I'd wait until then, if it doesn't come, then get a pregnancy test. If you're having symptoms, then maybe taking a urine pregnancy test would help you alieviate your fears.
good luck.. let me know what happens. I'd be surprized if you were pregnant. It's very unlikely.
If you aren't pregnant, you should go on some type of birthcontrol. If your interested, I can give you some help in that area also....
