Hi, I was just wondering if anyone could help me. I missed my pill on saturday the last week of my pack of cerazette. I had sex on the sunday twice and then had a dark brown discharge lasting a few hours on the monday. and then missed it on the wednesday (1st week of new pack) and had sex again with my boyfriend on the saturday. This was over a week and a half ago and since that ive had very tender breasts and a tingling feeling in my stomach. could i be pregnant?
