Ovulation date

Rukea

According to my <a href="https://play.google.com/store/apps/details?id=com.glow.android">glow app</a> I ovulated on the 24th feb but I feel I may have ovulated yesterday as I had a chunk of egg white cervical mucus n I’ve had a dull constant stomach ache - would that mean I ovulated yesterday n not on sun 🙁
