So for the past few months I've started taking tests 5 or 6 days before my missed period but this month I've managed to hold off! I guess I'm sick of seeing the negative tests. Af is supposed to come Wednesday and I'm starting to get antsy. Usually by this point I already know I'm not pregnant but not this month! I haven't had many symptoms, just increased cm a few days ago for about 3 days and my boobs are sore when I run or dance...I teach kindergarten! We dance :) do you think it's too soon to test? Should I hold off to see if af is going to show?
