Do you think I missed my peak?

Can you ovulate without a positive opk? I think I have ovulated already as my body is acting like I have. I don’t do bbt. I have been taking metformin to help my irregular periods. I don’t remember doing opk on certain days is why I’m asking. I didn’t think I’d ovulate so early is why I wasn’t consistently doing opk. I did have cramping and ewcm tho. Then it turned into creamy cm.
