Positive OPK after Ovulation ?

I thought I ovulated CD17 (positive opks and bbt increase) but yesterday CD21 I got another positive opk (looks the same as CD17’s positive). Any thoughts? I have about a 27-31 day cycle and my luteal phase length is usually 12 days. Any input is appreciated.

Also, my temps look normal. Like my pre-O temps and post-O temps are within my usual range so that’s why I’m pretty sure I already O’d!!

Ive also skipped a few days preO with my bbt as I kept forgetting or was “trying not to try”
