Testing on my birthday 2/21!

Imogen • Baby 1 with IVF born July 2016.
I'm CD 19 and have decided to wait till AF is due before testing. I think a false negative would just make life harder right now and how great would a BFN be on my BDY! It's been around 13 months ttc and I have a bit of a feeling about this cycle! 
​If you're a praying type, would love you to petition God for this one!
