Ovulation worries

just me

Hey I’m Ttc baby #1 I have pcos have been Ttc 30 months. I’m on a medicated cycle. My last medicated I had an lh surge cd15. Here’s where my question comes in, my test look different from last time than this time.

The round before this

This round

Should I be worried that they look so different at the same cd? I’m currently cd13 and I’m worried about how many tests look, they are all over the place.
