Opk help!! First time user.. would really appreciate some advice!

M

I’ve been testing since my predicted ovulation date CD16. I got EWCM on CD 9 / 10. I thought maybe I was ovulating early but dismissed the idea... I only have limited opks and just used my last one. It’s now CD 19 and it’s not even an inch darker then it was two days ago... it’s my first time using opks. Do you think I’ve already ovulated? I also put my low LH surge into glow and it hasn’t moved my ovulation date like it has before. I can’t opk anymore so now I just have to try and have sex regularly but my partner has a low sex drive so it’s going to be hard!! I’d really appreciate some advice :) xx
