Have I ovulated?!

Krissy

I cannot tell if I have ovulated or not. I’m not using OPKs, but am using an ovulation microscope. I had full ferning for two days and then partial on the third. I had bad cramps from my left ovary on the 25th, and I was almost positive that I ovulated, but it doesn’t line up with my BBT. Any help??? 🙏🏻🙏🏻
