14 dpo BFN

My period was supposed to start today, it hasn’t yet 🤞🏻. I’m not getting excited though because even though my opks confirmed the predicted ovulation date, I had mittelschmerz two days after that. I’m not 100% sure when I ovulated. If it was two days later, it would push my period back too, right?

Update: AF came a day late. ☹️
