Missed period, BFNs

Caitlin

This is my first month TTC. For some reason I just have this strange feeling that I am having pregnancy symptoms when maybe I really am not. (Nauseous consistently, lower backaches, etc) My AF was suppose to show today but didn’t. I have been testing for a few days but BFNs only. I ovulated on the 20th and I currently have a lot of very watery CM. Is it possible to still be pregnant?
