First time charting & need help please 😅

I started testing for ovulation on the 10th July

(<a href="https://play.google.com/store/apps/details?id=com.glow.android">GLOW app</a> wrong for ovulation dates 🤷🏼‍♀️)

July 13th was my peak on ovulation tests

My first ever time using BBT

Readings are for July 11th, 12th, 14th, 15th, 16th, 17th ( I forgot 13th)

Am I somehow doing the BBT wrong or did I ovulate? Totally confused as first ever time trying to BBT. Any help would be very much appreciated
