Would Letrozole make an OPK positive??

Stephanie • TTC #1 👶🏼💚🙏🏼

Took one today and it was a solid smiley face..

I took letrozole 2.5 Cucle day 3-7. Had my monitoring visit on cycle day 11 and my follicle was only 11mm. They upped me to 5mg of letrozole and it’s only been two days; could I really be ovulating this early????

My next monitoring visit isn’t until Thursday.

Any advice helps! Thank you!
