Yay for spaying and neutering!
No matter how much the kitty drives you nuts, though, DO NOT have her spayed until she is totally out of heat.
When she-cats are in heat (maybe other animals, too), their ovaries swell up in some way that really implants them in the body. If she is spayed in the condition, there could be parts of the ovaries which do not get completely removed with the basic slice-and-scoop surgery. What that means is that she will be sterilized, but will still go into heat! My mother did this to her cat, finally broke down and got her fixed while she was in heat, lied to the vet, and ended up with a yowling, presenting, gooey kitty anyhow. Years later, kitty finally got a follow-up surgery to remove the remaining ovary part, which was covered in scar tissue and took about 4 hours of surgery to locate and remove. Kitty has a massive wound and was in pain for a while.
Oh, and don't cheap out on the meds: your vet should offer a liquid painkiller for your special girl after her surgery.
