Before I started birth control pill I had a 33 day cycle. I only took birth control pills for a week. When I stopped taking them on may 15th my period came may 25th which was a 25 day cycle. Then on June 11 I had unprotected sex with my bf. I had what I thought was my period on may 15 and 16 but im not sure. then on 18 and 19 had light spotting. My periods usually last 5 to 6 days. If that was my period then I had a 15 day cycle. Today is July 5th and I was supposed to have my period today if I had a 15 day cycle still. Should I take a test or just wait to see if it comes then next couple of weeks ?
