Implantation bleeding?

I’m super uncomfortable to share this but I feel like I have to ask after not finding anything in previous posts.

I’m slated to have a 34 day cycle this month. I O on CD 20 or 21 and I had this faint, brown, clear discharge on toilet paper on CD 31. It was the only time I saw it. It couldn’t have lasted long. I was worried it was my period at first but no sign of AF.

Does this look like implantation bleeding?

TIA!
