Question

Kristine
My SO and I have been TTC #1 for a few months now. AF was supposed to be here on 5/18/15 and has yet to make an appearance. I've taken 3 HPT and have received BFN on all of them. My boobs have started to feel a little tender the past 2 days and my CM is creamy and odorless. Could I be pregnant now and the HPT aren't picking up on the hcg levels?
