High OPK on cycle day 9!

Veronica
Hey ladies!! I can endo and this month was my first month on Femara/Letrozole. I tested yesterday on cycle day 8 and got a negative OPK. I tested again this morning and got a "high" or flashing smiley face on my OPK. Has anyone else ever taken this, ovulated super early, and got a BFP?! I go in for my ultrasound this weekend to see how big the follicles are and am hoping for the best!!
