Ovulation spotting?

Kristy • Married the love of my life🤵🏻👰🏻4/21/18. Lost our angel baby at 11 weeks👼🏻 12/6/18. Had my rainbow baby boy👶🏻 3/27/20. Lost our 2nd angel baby boy at 21W3D 6/3/2022 👼🏻. Pregnant with rainbow baby #2.

Quick backstory. On June 3rd, I had a d&e at 21w3d because my baby had a neural tube defect. I got my period back 5 weeks later. On cycle day 10, I noticed that I had a little bit of reddish spotting right before my fertile window started. I had spotting again on cycle day 12 and then yesterday on cycle day 15, I've started this brown spotting. I've been tracking my ovulation through OPK's and I haven't gotten a high or peak result yet. Has anyone else ever spotted during ovulation? (We want to try and conceive again and are having unprotected sex).
