Help! Is my opk positive or picking up hcg?

Breezy Mama 🌈💙

I had a D & C just over 2 weeks ago after a miscarriage. My hpts a few days ago, both lines were the same color. I took an opk yesterday out of curiosity and it came up super positive ( test line much darker than control) I thought maybe it was picking up hcg, so i took another hpt. This time second line on hpt was hardly visible. opk still very dark today. Thoughts?!
