I was supposed to start a pack on saturday night-Feb 2 but instead started it on Monday night- February 4th. Unfortunately never did a catch up so I am currently two days behind. I had unprotected sex on Feb 8 and Feb9th.( 10th and 11 th day from my period)...my period are always 100% regular with the pill. I've been on the pill for over two years and never missed a pill ! I am soooo nervous right now. Do I have a high chance of getting pregnant?
