Hi this is Dr. Hill. The average gestation for a queen is 54-72 days. Unfortunately, if she is truly only 5 weeks and has some bleeding, then she may be losing the babies. You should take her to your local veterinarian and they should be able to help determine how far along she is and if there is anything that can be done to help. A small amount of discharge from the vulva does not always mean that the babies are at risk, but can be a sign of miscarriage. Feel free to ask additional questions.
