Help! My opk looks so close to the control line but maybe just a hair lighter?! What do you think? Is it positive or not?

Ever since I stopped breastfeeding my now 20 month old last spring and then my period returned this last summer, my cycles have been messed up and vary from cycle to cycle. They range from 28-39 days now. Prior to having my son, they were about 33 days long consistently. Anyway, Glow said I was to ovulate yesterday at CD 19 but my opk was too light. This morning I had a temp dip by 0.4 (which I used to get sometimes right before I ovulate- that’s how we conceived my son) and now my opk is darker today as well. I’ll take another opk in a few hours to see if it gets darker.

I just need help as my inconsistent cycles have made it harder to conceive this time around!

What do you guys think? Any and all feedback is welcomed as well as positive vibes! We really want to get pregnant soon, so our kiddos are less than 3 years apart. ❤️
