I'd say don't worry hun. I heard a lot of girls can feel like that after having sex for the first time. But if ur still feeling like that after having missed ur period, then i'd say test. But until then, try not to worry about it.

Sex brings on alot of responsiblities and possibly being pregnant is one of them. There are methods of birth control out there, but none are 100% effective except for absitence. Maybe sexual activity should wait untill your a little more prepared for the extra stuff that comes with it.

As far as pregnant symptoms go, I really don't think you could be having symptoms so early. Don't worry about it hun, because stress will make your period late. Good luck!

My wife and I knew exactly 14 days after insemination(sp). We had to use a fertility specialist and so my wife was peeing on sticks like 2x's a day for 3 days and then when she was confidant the second line was real, we went in for the blood test and she was definatly pregnant. The blood test was 14days post and the pee tests were 10, 11, 12, and 13 days post and they were all positive and positivly expensive!

Buy a preg test if you think you are, you probably are right.
