I had unprotected sex 7 months ago and I've had my period. I had unprotected sex 4 months ago, and I still had my period. 3 months ago I had unprotected sex as well. All 3 times I had sex, no semen came in contact with my vagina. The last time I had sex (3 months ago) I was fine. A few days later, my period came. A month later, my period came. But as of today, I am 10 days late for my period. The first period I've ever had was maybe a year ago. And my period has never been late before. So now I'm freaking out because there's a possibility I'm pregnant, considering my period is late. I have been stressed lately, so that may be a cause of "no period" too. I haven't had any spotting or anything. There's no sign of blood at all. I haven't had cramps or mood swings. I'm just freaking out because I'm too young to be a mother, and id like to pursue my dream of finishing high school and going to college. I really need help because I just do not want to be pregnant.
