What is going on?!

I don’t know where I’m at right now. I took my last active bc pill on June 23 and had my withdrawal bleed June 26-28. I had very light pink spotting on July 18 and then brown and some red spotting July 19-21, each day only using 1 liner, mainly seeing it when I wiped.

I wasn’t using opks or tracking bbt last month as it was my first month off bc so I don't know if I ovulated or not. Originally Glo had my ovulation day as July 9, but changed it when I put light af on July 18-21. 🤷🏼‍♀️ I've taken 4 hpt all negative and got this opk today. Am I close to ovulating? Anyone else have a similar experience coming off bc pills? 🤯
