New to ovulation strips

*these were taken this morning at 9:50-9:55am.*

I’m new to tracking ovulation. I’m on day 11 of my cycle. Period was April 2-6th. I took letrozole 2.5mg may 4-8th. Does this mean I’m about to reach my ovulation date? Should we start trying now? Not sure how all this works…. Conceived my first daughter without any issues but after my miscarriage a year ago i have not been ovulating correctly and my progesterone levels were very low. That’s why my OB put me on letrozole.
