Hi, I've been taking cerazette for 2 and a half months now, I'm a bit slack on taking it at regular times, but the week before I had unprotected sex I had taken it every single day. I haven't had a period whilst I have been on it, but recently I have had these weird pains in my lower abdominal muscles (not like period pains, all the way across) spasm's in my stomach muscles and started craving certain foods. This has been going on for a week and a half (along with occasional lower back pain) and it's been about a month and a half- 2 months since there was a chance I could have gotten pregnant. I go out clubbing and binge drink and am a heavy smoker but hadn't been sick because of it, does this affect the pill and is there a chance I could be pregnant?
