Glow ovulation prediction

Hey ladies,

Is anyone else having issues with the ovulation prediction in the app?

For the last few months my predicted ovulation day has been way off according to the tests I've been using.

Yesterday should have been peak day for me but there was such a faint line on the test I could barely see it...

I don't know if im just over thinking it or if my body is just playing up but has anyone else had a similar experience?

We have been TTC for 8 months and I'm starting to worry that my timings have been wrong this whole time!

Thanks
