Ovulated twice?

Bit of a background..

My cycles are usually 36 days give or take a 1-2 days.

Iv been tracking CM and using OPKs and I ovulated (apparently) on CD 23.

I’ve tested pretty much every day since 10dpo and they’ve all been negative apart from maybe 3 tests which me and other people could swear we saw a vvvvfl 🤷🏼‍♀️

Anyway I’m now CD 55, Iv had a blood test which came back neg but Iv also just had the most positive opk Iv probably ever had. Is it possible to ovulate twice in a cycle this far apart? Or have I started a new cycle without having a bleed? Is that possible?

If I’d had my period at my normal time then I would be in my fertile week right now.

WTF

Anybody else had similar? I’m so confused.
