hey i am a teenager and i had half unprotected sex and half protected. it first started off without any protection then like 2 mins after with protection. After the following day, i started getting a weird little cramp in my ovary and i told myslef no it can't be. I'm almost do for my period but i'm worried because i still haven't gotten it i am so anxious to get it. I wonder if i am pregnant sometimes i think i might be. but other times i don't think so. My breasts are not swollen and all i feel is a little cramp. help!!!
