Good afternoon, I need some help. I had a one night stand and the guy came in me however I was not ovulating. I am on the contraceptive pill but just to be sure I took a plan b the next morning. My period came a few days later but I’ve had my period almost 2 weeks now. It hasn’t been too heavy at least but what’s going on? Why is my period so long. Do you think I could be pregnant. I’m worried?
