Possibility?

So today at work one of the supervisors comes in and straight out says you're pregnant. Now mind you according to everyone who's worked with her she's been spot on telling them their pregnant. I kind of laughed since AF just left yesterday. I looked at her and said its pretty much impossible since AF was pretty heavy.  She comes up to me privately and says that she wasn't kidding and she sees this "glow" about me and that I can be even if AF just left or I'm gonna be this cycle. She said I know it's hard to believe, but I'll  be praying for you and for you to see that bfp soon! It gave me some hope just to know someone else is praying for the same thing we all are. I figure, what's the possibility she's right? What are you're thoughts?
