OPK predicting pregnancy

Krissy • 🏝🌻🍄

Disclaimer: this is purely an experiment. I’m fully aware I shouldn’t rely on an opk as a pregnancy test BUT has anyone ever had a baseline change just before their expected AF date and ended up pregnant? Top photo is 3 days before AF this cycle (today), bottom is 3 days before AF in April (each month has been similar until this one)
