She should be spayed at least one month after she comes out of heat, and at least one month before she is expected to come back into heat. That typically leaves a three month window of opportunity.

It would get little puppies inside her.
Unless you want your dog for breeding, please get her spayed! Spaying the dog stops her from going in heat. Also if you do not, 50% of female dogs that have not had puppies and are not spayed get Pyometra, a disease of the uterus.
This is a common sign of estrus in dogs and is a result of your dog's biological drive to find a male and mate to produce puppies.
A dog's heat cycle will last it's course whether the dog is bred or not. It is possible for a dog to be impregnated by more than one dog at the same time, resulting in mix breed puppies. So, no, it will not stop just because the dog is pregnant.
