Ovulation Confusion

Britney

So this is my first month TTC and I’m lost lol. I have been testing my LH every morning and every evening and after last nights I thought this morning I’d have a positive but it’s lighter? Could last nights have been positive even though it’s not as dark or darker than the control line? Or is this possibly me not ovulating? I had lower back pain during the day yesterday like I might’ve been ovulating but idk. Any thoughts before I spiral?
