Waiting game

I was ttc awhile back and had a couple m/c. Since I've stopped ttc but since my last mc now have conflicting info on apps. One says I start AF 2 days ago, one says in 2 days. Ugh which one is it? And I feel like I have too much going on now for a baby anyways! Dang it! Just stressing. And my boobs are super sore and have been for days. Not helping... AF? Where are you?
