Answer
Dear CJ,

Rabbits are induced ovulators.  This means that when they mate, the female ovulates, and pregnancy is almost a sure bet.  So if the rabbits are mating, the female is most likely pregnant.

You can find a good vet to help you here:

Bleeding from any orifice is not normal for rabbits, so I would get them both to the vet for a full wellness check ASAP.
