I had my nomal period October 2nd it lasted the normal four days around October 14 - 16th I had unprotected sex. On the 28th I had very light bleeding & it stopped on the next day. My period is never irregular but now this month it hasn't came at all. Every pregnancy test says negative. What's going on?

Hi BrianaWi... not an OBGYN, but welcome to AMHD,

It may be an off cycle, so see what happens when you would expect your period for December. If it doesn't show, either try another home pregnancy test, or see your doctor for a test there.
