Letrozole- opk? Help please!

Amanda • having a hard time conceiving due to pcos, losing 2/10 of my left ovary and entire left fallopian tube. Ive done 4 rounds of clomid, 9 of letrozole, 2 letrozole with trigger shot and had my first IUI on 12/11/18. baby dust to all!!!!

Was switched to letrozole this cycle, I've been testing since cycle day 10 and today is cycle day 14. Is this a positive opk? Or almost? Is it to early to be ovulating if I took letrozole on cd 5-9?

Thanks in advance!
