Cd21 check plz respond 😭😭

I go on Saturday to confirm ovulation. First cycle with letrozole. Quick question what are the chances i ovulated? Had a 3 day surge peak, 2 days ago i had ovarian pain on my left side (dull/burning pain in lower left back and left pevis) along with more pelvus pain last night? I been having some dull aches today in my pelvis but they dont hurt Not to mention 3 days full of fertile mucous (all 3 days if my positive tests). Im so scared its gonna be 0 or a low #😩
