I think AF is a tease!!!

Jessica • Edd 11/9 #3 after losing 6 mo old daughter last July & having a tubal reversal in September. Hoping for a rainbow baby!
So I'm 2 days late now but got a bfn on my hpt.  It got me thinking.  AF is such a tease! I mean my body is like clock work with my period usually so if she shows up a few days late after we've been trying so hard to get prego I'm going to be so disappointed!! :(. I mean if she's coming it'd be nice for her to just stay on schedule! Jeez! Lol
​Still not counting a bfp out.  Anybody else dealing with this? I'm wondering how long I should wait to test again....?
