UPT—yay or nay?!

Brit

I have been on OCPs for 15ish years due to PCOS. Have been off x 3 cycles but am irregular usually by 2-3 days. I am 8 days late and this is my UPT. I also had one sit on the counter and come up positive the next morning but the subsequent 2 were negative. Now this one is eh. Anyone ever have anything g similar?
