Help with OPK please...

Elizabeth • Momma to three beautiful children, 8 years, 5 years and a newborn. 😍
For the last 2 days I have gotten what I have posted below...almost positive opks. I test two or three times a day (morning, noon, night)...got the darkest one yet last evening at 8 pm (not pictured) but the test line was barely lighter (I mean it was SO close-i had to do a double take). I know what a positive is because in prior cycles I would get them for maybe 12 hrs at a time. Well, this morning when I woke I tested and I'm getting a way faded test line. Its still there but not even as dark as pic ive posted of yesterdays. So, now I am left wondering. Was last night's almost positive, my positive?? I have bd'd both Sunday night and last night...
