Hi there. Ok so I'm starting to get a little worried. My last period started on July 29th and ended on Aug 3rd. My boyfriend and I had unprotected sex on the 7th but he didn't ejaculate. We then had unprotected sex again on the 17th only this time I took the "Option 2" Pill. These pills have thrown my cycle off in the past but it's rare. On another app it says my period should have started a few days ago and on the <a href="https://play.google.com/store/apps/details?id=com.glow.android">Glow app</a> it says it should start tomorrow. Should I be worried?
