well the thing is, i lost my virginity 3 and a half weeks ago and have done it 15 times since. When i had my first time i had been on loestrin 20 bc pills for about 23 days, the doctor recommended i waited a month before using the pill as contraception. Since i have been careful, never missed a pill and have never taken one more than an hour late. But... we've never used a condom. For the last week i've been feeling really nausicious when i wake up and my stomach has that swollen feeling, like when your period is near, but mine isn't. What do u think the chances are that i'm pregnant? I know its probably just me being silly, but i admit i'm a little worried! thanks for any help u can give.
