Not sure if letrozole worked this month :/

Started on 2.5mg days 3-7 after using provera to induce a period. I got a high opk on day 10, I also had an HSG that day. We didn’t have sex at all that week just because we had a lot going on. CD 15 I had what felt like ovulation pain but when I tested it was negative.

Today is CD 19, Glow says tomorrow is my ovulation day but so far I’ve had vvvvvvfl on my opk strips. I’m feeling a bit hopeless at this point and ready for my friggin period to show if it’s gonna.
