How would yall word this?

Me

I petsat for a family friend the other day. Normally she doesn’t pay me right after but usually will by a day or two afterwards. This was Monday and now it’s Thursday. I’m thinking about giving her one more day before saying something but when and if I do, I don’t want to come off as rude. I was thinking of saying “Hey ___, I was just checking to see if you forgot payment for me watching the dogs” does that sound alright?
