hiya guys um i had sex with a friend about a week ago and i was in my fertile window. he put on a condom but we were so rough i wouldn't imagine that thing holding on. he stopped mid way to fix it, so i think it ripped. i'm on the pill, but i feel sick every morning and my appetite has increased SOOO much. i have headaches and my boobs are sore. MY PERIOD IS NOT FOR ANOTHER TWO WEEKS :((( how long should i wait to take a pregnancy test? i'm 16. thank you.
