I lost my virginity 3 weeks ago on December 24th. We used protection. On December 30th we had sex again and we used protection. He didn't cum in me but the first time he did, he came as he was pulling out. I've been so paranoid ever since. I read that spotting is a sign of pregnancy so I've been wearing panty liners but nothing came down, until the 15th which was when my period was supposed to come and I guess it did but it's dark brown and it's coming down a little. I really need help because I'm so scared about being pregnant. PLEASE HELP!!! Is it because I've been stressing so much that my cycle or body is changing? I also don't have any cramps.
