Math help lol

I had unprotected sex 6 times this month:

Three times during glow’s predicted ovulation week (24, 25 and 26 days ago)

Once 16 days ago and once 17 days ago

Once yesterday

I got a near-positive (I think?) opk about 14 days ago

Everyone on /faint-lines/no-bfps said this was negative. I thought I saw a line. With this timing, do you think I might still be pregnant? Or highly unlikely? I’m also a week late? And I never am?
