i had sex on Jan 31, got a normal period on feb 7, and now I'm 2 weeks late for my second period. It should have came on march 5th. I've been sick with a bad cold for a few weeks now, and I had a small fight with my friend. Could it be stress? We used condoms and I don't think it broke... helpppp I'm so freaked out and I can't tell anyone because I come from a really conservative family. Should I see a doctor, and can I be pregnant? If I'm not, why would my period be late?? HELPPP!!
