The answer is no.
Rabbits are induced ovuators. That means they have no heat cycle, but breeding them causes them to be in heat, which basically ensures that they will get pregnant almost every time. Their 'private part' may look darker red when they have reached an age when they are ready to breed, but not with all rabbits.
If your rabbit's genitalia is swollen, this is a sign of illness or injury. Look for other bad signs, and bring the rabbit to a "rabbit-savvy" vet as soon as possible. See the related questions below for info and links.

Yes, it is normal for the vulva (the outer area of the female genitals, outside the vagina, including the labia) to swell, and for blood or other fluids to drip from the vagina. When the dog is in estrus, she is fertile, so you might want to keep her indoors to prevent pregnancy. To avoid the mess and behavior problems often associated with estrus, and unwanted puppies, have your dog spayed.
Dogs do not have periods. When a bitch goes into heat her teats may become enlarged.

Rabbits do not have periods like humans do. Instead, female rabbits go into heat, which is called estrus. During estrus, a female rabbit may show signs such as increased aggression, restlessness, and mounting behavior. These are not the same as period symptoms in humans.
