Flo vs Glow

My glow app says i likely ovulated on the 30 which would put me at approx 6dpo. My Flo app says i likely ovulated on 26th, which would put me at 10dpo.

Both apps have AF estimated to start on either the 13th or 14th....

So when would you test?/which app has been more accurate for you?

If you asked me this question 2 months ago id say Glow... but the last 2 months Glow has predicted way off..

Lol

I woke up this morning with some indigestion/nausea. Im not using OPKS because its too stressful...so we are just doing calendar method.
