12 Days Post IUI

So, what I did I do first thing this morning while Chad was asleep?  I tested.  BFN.  He was pissed that I did it and I'm disappointed in myself too.  There's no way it will be positive in just 2 days.  I have heard that sometimes the home tests aren't reliable and that blood tests are 100% accurate.  Still no period but my back still aches and I just woke up from a nap.  I haven't felt any pains at all in a while though.  Tomorrow morning I have bloodwork at Dr. Smolen's which will help pass the time.  Maybe all my "symptoms" are just from the progesterone suppositories I've been taking.  I have a lot of praying to do!
