OPK help!!

Ni

Is this positive?? It’s my first time using these opk’s and I’m a bit surprised by this as Glow said I’d ovulate Saturday (it’s only Tuesday) and My CM is really hard to gauge. Kinda blobby and slightly stretchy (sorry TMI) but there’s also not a lot, I have to dig to find it 😂

I’m also confused because while I usually have 29 day cycles, my last one was 43 days for some reason, likely stress related. I’m currently on day 13 of my cycle.

Any help is appreciated!!
