AF DUE 24th on First Response App, Glow says due 4/26

I was using a first response app to track my cycles for months. It was always super accurate. Last month my cycle was a day late and a day shorter. First Response says I should've gotten AF on the 24th. I just downloaded about 4 months worth of info into Glow last night (new here) and it says the 26th. Currently having really sore boobs. I use to have them when AF started every month and I haven't the last 4-5 months. Mostly the nipples are sore. I had mild cramping today and I'm hoping AF doesn't show up tomorrow. My husband is in the field for work and I would LOVE to surprise him with a BFP when he comes home. Blahhhh. This post is mostly a vent, I don't talk to friends and family about TTC much at all.
