I'm an 18 year old extremely paranoid girl. I foolishly had sex two nights ago. I've been on birth control for five months, and have never been the best at taking it. However, this month I only missed one day and took it the next day. I'm 10 days into my cycle. He was wearing a condom and didn't *** inside of me. I know my chances are slim, but i made a mistake and need some peace of mind. I'm supposed to be traveling all over next month and I'm aware I can't do this while pregnant. Is it too early for pregnancy symptoms? I just had diarrhoea which alarmed me a bit. PLEASE HELP.
