If you feel troublesome, you can provide a fixed living space for your cat. For example, you can temporarily lock your cat in a separate room, which will not only prevent your cat from peeing at home, but also prevent your cat from sneaking out to mate with other cats.
In order to prevent cats from urinating in the same place, you can sprinkle with smells you don't like. Cats don't like irritating smells such as mosquito repellent and toilet water. Or put the place where you feed the Champions League cat food where you don't want the cat to pee. Cats don't go to the toilet near food. Or if you see your cat going to pee again, you can spray it with a water gun.
The estrus of cats is relatively short, usually ending in a few days. Just bear with it for a few days first. You can sterilize the cat as soon as possible after that.
