For those who have had the Mirena... I went and picked mine up today and they told me about the pill I have to take the night before and said "Is there any chance you're pregnant" and went on to talk about how bad the pills are if you are, and I am just curious now (because I have this irrational fear that even if I am using several methods of protection, if you're having sex there's the chance of pregnancy) but do you generally have to get a pregnancy test before they ask you to take those pills? Or should I get a stick to pee on just to be safe or...? I am 99.9% certain I am not preg.... but when she said that it freaked me out.
