Yes, it's possible she was still in heat when you took her in. Rita had very long heat cycles and sometimes went into heat back to back due to hormone imbalance.

I just kept mine as calm as possible and did a lot of crate rest. Rita acted pretty blah for the first day or two after her surgery and then she tried to go back to normal behavior while I tried to keep her from hurting herself until she healed.

Some dogs are a bit more sensitive to the spay surgery than others. You could ask for pain meds, i personally didnt but my dog was fine. Spaying a dog in heat from what i understand is a slightly more difficult procedure even though im not sure why.
For now i would just wait it out and make sure she takes it really easy if shes bothered.
Is cleo crate trained? Maybe some crate rest will help for a day.

From what was told, the surgery is more complicated because the uterus is getting increased blood flow and is engorged. It takes the vet a bit more time to sever the veins and arteries and to remove the uterus because of that.
