Can anyone share some insight/ suggestions?

This is our 5th month ttc, i've been pregnant twice and fallen pregnant first opportunity both times, high fertility runs in my family. I had a copper iud removed in October and was told fertility will return in 36 hours-3 weeks (obviously depending where I was at in my cycle) I've been using opk's and the only month i've got a peak was December on CD19. January I ran out of opk's so couldn't continue testing and now this month my line started off looking like it was close and is now gone.

I'll attach photos of my cycle (the 35 day one was the month my iud was removed), this months calender, this months opk's and December's opks.

I feel like i'm not ovulating? I asked a gp about testing and they won't until it's been 12 months because we are 24 and 25 but something just feels like it's wrong and i'm really getting down now.

Any help or advice is so appreciated :(
