I was supposed to get my period on July 5th according to glow but I have not gotten it yet. I am sixteen and My boyfriend and I had unprotected sex less then a week ago, but he pulled out after only a few seconds because we were too nervous. My period is sometimes irregular and I have not been sleeping much lately. I have the usual symptoms of my period and I have taken two pregnancy tests and both came out a clear negative. What do you think?
