I knew someone would answer my question like that. Haha. I should have been more clear in what I was asking. I know most women experience swelling of the breats and other symptoms of what might happen to a woman who was actually pregnant. but that's not what I'm asking. I'm saying, if by having sex a few days ago, I became pregnant, would the symptoms I would get if I wasnt on birth control appear eventhough I am. it's confusing but I'm not sure how to word it exactly. As of right now I will have to wait 11 days until I'm supposed to stop taking the pills to allow myself to get my period. And if I dont get it, then obviously I'm pregnant. The pills don't make me nauseas, so if I was pregnant, would I start feeling nauseas within the next few days? And then I'll know I might be. Or, will nothing happen because my body alreay thinks I'm pregnant since I'm on the pill. I realize thats what the pill does, tricks your body into thinking your pregnant so you don't get your period. But I don't know if i can wait 11 days!!!
