Okay, well, I've been on Loette (contraception). I started on Tuesday, which is also the day I was meant to get my period, I took my first pill in the morning by then I normally have my period , this time I didn't, and I still haven't got it, is there any chance I could be pregnant, or is this just a one off thing? Is loette causing this? I did have unprotected sex a few days before. Could loette still be able to stop me from falling pregnant though. Maybe 2 or three days before I started loette I had unprotected sex. This is a concern to me. And I need to know, as its bugging me.?
