Is this a good sign?

Briana

According to Glow, AF was due on Friday- she was a no show. According to one other app I use, AF is due today (Sunday). It’s 4:00am on Sunday. I work 3rd shift, and just got home. So far no signs of AF other than mild cramping. This is what my CM looks like. I know nothing about judging CM, lol. Help? Is this a good sign for a BFP?
