Early ovulation??

I’m on CD 8, my period ended yesterday morning, I started letrozole on CD5. Today I took an ovulation test (not fmu) and got what looks like a positive. Is it possible to be ovulating already? I haven’t even finished taking the letrozole for this cycle yet lol

The last cycle I used letrozole I got a darker than usual result the first day after my period but not nearly as dark as this and it ended up going down and then coming back around CD14. I’m not temping this cycle because I had a chemical a couple months ago and I’m trying to be more chill this time around, then this happens!
