How to change ovulation day on calendar?

Ell • Married to my best friend 💖 TTC 👶🏼 #1 ⭐️

I had a positive OPK on Thursday evening it was negative Friday evening so assuming I ovulated either yesterday or that I am due to ovulate today. Glow is saying I’m now out of my fertile window and that I ovulated on Thursday. Is there anyway to change this!? I have logged my LH surge but it hasn’t changed.

Thanks ladies x
