So confused. BFN

Erica

We DTD on Saturday morning, I got my Peak Fertility the next day, Sunday evening. The following Saturday I had spotting. I’ve been testing the past few mornings with Wondfo, as well as a FRER yesterday and they have all been 100% BFN. Glow predicts AF today (cycle day 30) other apps predicting AF within the next few days, Wednesday being the last expected day. No AF so far but she usually arrives in the late afternoon. Any advice input suggestions ANYTHING would be appreciated. 😔😔😔😔
