I got my first depo shot on March 24 and would have been due to get my 2nd shot around June 2nd if I remember right. I had unprotected sex on May 9th. I did not get my second shot but have not had sex since May 9 (unprotected or otherwise) I had a period that was spotty and lasted for about two weeks at the end of May but I have not had any bleeding since then. What I want to know is if I could be pregnant?
