Clear blue OPK still no LH surge

J

First month using Clearblue digits opk tests.

Glow predicts my ovulation to be this Sunday but today at noon I did a test and still no surge 🧐 ususally glow is on point with tracking my cycle... anyone have experience with this?

When I used the cheap opk test strips i always got two days of positives!!

Ugh maybe I just truly ovulate later than I thought..

Thanks in advance for any input, advice or experience🙏🏼🤔
