Bfing, opks, and confusion. No return of cycle

I have been breastfeeding for 10 months, and still no return of AF. I started taking opks here and there a couple weeks ago, just to see if I'm even ovulating.

My son still night nurses, which I heard is a big fertility downer but I'm not too sure. He does eat 3 meals a day and 2-3 snacks...nurses obv. At night, then around 830am once when he wakes up from his nap around 10-1030 then will just have a few brief, less than 5 min seasons of nursing until he is ready for bed around 8pm.

To the point, these are my opks. The very bottom one is from this am, with fmu. The one right above it is from last night.

When I bought my opks I bought a pack of two pregnancy tests. Not paying attention I bought the first response rapid results, instead of the early response.

I took one test when I first started taking the opks (not pictured) bc I t was clearly negative and I've read that those tests are no where close as sensitive as the early response.

Well I took the other test Friday afternoon as I have not been feeling good, sick to my stomach and pretty tired.

I know you ARE NOT supposed to take the test apart but I was having line eyes, and out of ignorance I personally don't understand how opening the test up effects the results (unless it's a digital of course bc those usually have two line reguardless)

I see a faint line but I'm not sure bc I honestly can't remember if I took the test apart within 10 mins or later than that, thus obv. Making it invalid if so anyway.

What do you guys think? Maybe my body is having a hard time releasing a egg, or are these opks possibly telling me I could be pregnant?

Also, I never did I opk on Saturday so I don't know how dark or light it would of been so there is a day gap between the bottom two opks and the third one from the top.

Thank you for your time, I'm basing whether or not I go buy another test (the right one this time) or not off of what you ladies think
