TMI 9dpo

So.. this is really embarrassing and i don’t know if it’s pregnancy related, AF related, or progesterone related, but for the last 2-3 days I’ve been having orgasms in the middle of the night. My dreams aren’t sex related and I know my husband is fast asleep so he’s not doing anything. I normally never experience this. Can someone give me advice on what they think it is and how to stop it? It really hurts when it happens. I feel crampy afterwards and can’t go back to sleep.
