Ovusense ladies help!

Ja

First cycle using Ovusense which is vaginal wearable

I’m wondering why it’s showing o yesterday cd 14 but why is it showing I’m in my fertile window after. I thought it was before.

I only use the app for the sensor. But I had peak cb 12 in the pm and cheapie opk blazing cd 13 until 14. Ewcm all days. Thanks
