So about a week and three days ago I had unprotected sex three times in a row but the guy pulled out every time. I'm very concerned because I was supposed to get my period two days ago and it hasn't come.  I'm feeling all the symptoms that you normally get when your about to have your period but it hasn't come, I don't know if I'm just stressed out or if it's just late or if I'm pregnant I'm so scared I cry every time I think about it. Please help
