My and my boyfriend had sex a week ago and I am paranoid that I am pregnant. I have been doing a lot of research and I know that there is always a possibility of being pregnant but there was no rips or anything in the condom and I am on birth control too. In the past month I have made sure that I haven't skipped or missed taking my pill and I take it during the night from around 8-11. Yesterday I threw up 7 times and I had diarehaa and passed out but I can't tell if it is a stomach flu or if I'm pregnant! Someone I know had the stomach flu a couple days ago and a lot of people are sick right now. I'm really young so I don't want to tell my mom that I had sex, even though she would understand still its not something I feel comfortable talking about
