All you Opk/cm professionals please help!!

So I thought I ovulated this month, 4/21&4/22 I got the positive opks, had the ewcm. You’ll see this in the first pic. Now today when I thought I was 8 or 9dpo, I’ve been having ewcm again so I did another opk and it’s positive (2nd and 3rd pics, sorry for the tmi ewcm pic). Anyone have any explanations or answers?? Am I just ovulating twice or is that not even possible? So confused 😩 also had some dark brown spotting this morning just when I wiped if that helps?

Also took a pregnancy test this morning and it was negative.

helps.
