UPDATED. Is this ewcm? TMI PICS!!!

Kellie
Hi I was just wondering if this is classed as ewcm? It's clear and stretchy as you can see but has a slight yellow tinge.. This is my first cycle on Metformin as (I have pcos and I don't generally ovulate) I have been doing ovulation tests and they're all over the place but I think I got a positive on cd20 and thought I got ewcm a few days ago but ewcm is new to me so I could have been wrong. I have had cramping here and there the last few days and last night/yesterday arvo had a pinching feeling in the pelvic area. I'm now at cd22. Here is a pic of my cm today and also what I think was a positive opk from cd20 (bottom test) what do you think? Tia 😊
