Based on my period

Breanna

So based off my period which was every 25 days since having my daughter in July I would be due the 19th which glow took into account. Ovia did not ! Which do I go by. I’d like to think glow right!?

I can’t ask my doctor as my first appointment is in 2 months since she’s out til then. 😑😆 and I won’t see anyone else
