I started taking Cerazette about two/three weeks ago it says to start taking the first day of your period and you have instant protection. Well my period started late in the afternoon and I was at work without the pill so I took it for the first time the next morning. On day 5 of my period I had unprotected sex and have since read that if you do not take cerazette on the first day of your period but you take it from day 2 - 5 of your period you need extra protection. im now concerned I might be pregnant as my nipples are enlarged and very erect and sore, im having a big break out of acne and im concerned because i am still taking the pill so if i am pregnant what harm would that do me or the baby?
