When did I O?

I only temp and check CM/CP. I don't do OPK so don't judge. FF says CD 16 and I think CD 18. What's everyone's thoughts?

I'd say cd 16

And here's the weird thing. I added in my CM/CP and it moved my cross hairs to cd 18. Now I'm really confused

I dont even bother with putting cm in for that reason. Some ladies get fertile cm after they ovulate. But...it IS possible you Oed on CD18..
