I lost my virginity 3 weeks ago, and I've been on the pill for a month and a half. My boyfriend didn't ejaculate inside of me but we also didn't use a condom. 3 days after me and my boyfriend had sex I had my withdrawal bleed (a period whilst on the week of inactive pills), now 3 weeks later im starting to worry that I might be pregnant. Yes, people often tell me I'm a total hypochondriac but I sometimes quite nauseous in the mornings and at nightime My tummy has also got a bit bigger but that could just be normal? We had sex a month into me taking the pill. Am I just freaking out because it was my first time or could I actually be pregnant?
