I've been taking Aviane combination birth control pills for a while now - perhaps eight months or so now. I take my pills religiously every single day. This current month I've taken every single pill within five minutes of a set time. The longest time I deviated from this set time was about two and a half hours during my first month taking the pills. Additionally, I have never forgotten a pill in the entire time I've been in birth control. Nevertheless, I'm still very worried about the possibility of pregnancy. I've heard those crazy stories where a woman managed to get pregnant while supposedly taking her birth control perfectly. I was wondering how likely these stories actually are and what my chances of pregnancy seem to be based on my birth control routine. I always manage to convince myself that I could be the "one in a million" case and end up pregnant.
