If you are confident Katie was in heat three weeks ago and there is a large amount of vulvar discharge I’d be concerned that the bleeding might be from a uterine infection or pyometra. If it’s a small amount of discharge it’s possible that she’s having a longer than usual heat cycle. Your vet would be able to determine whether or not she is still in heat with a physical exam and vaginal cytology to look at the cells in the vagina. I’d recommend making an appointment to see your vet if the bleeding continues.
