As long as its not oozing, a minor pink color is ok. You can safely put some neosporin on the area, deter her from licking at it, and if needed you can apply a cool compress..not ice..just a cool washcloth. If it turns red, major swelling, feels hot to the touch or does start to have discharge, then a vet visit is in order. Kudos to your for having her spayed :)
