Has anyone got any opinions on the best early testing kit? My AF is due Sunday, and I have one First Response left from last month. I know it says that it can detect the hormones 4 days before AF is due, but I'm going to try to leave testing till Friday. Who am I kidding!!! You know I'm gonna be on here first thing tomorrow morning telling you all I've took the test, I'm just so impatient! (I'm hedging my bets with the smilies!!) But just in case it is a BFN, are there any others that have worked early for other people???
