OPK said i ovulated on my period??

The first “CD” is when my dr told me to begin Letrozole because she said my period wasn’t going to come.

The “//CD” was when my period started!😐

I completed Letrozole around my “cd5” aka my last day of taking Letrozole.

I’d been taking opk throughout and it looks like it is positive opk during my period. My very last one i took 10 this morning and there seems to be absolutely nothing hinting at me ovulating any time.

What should I do?? I’m at a loss if I should keep testing/ttc or if I really ovulated during my period if that’s even possible.

Any advice?

I can’t talk to my dr as it’s a holiday and I’m on a military base.
