Sorry guys, my bad.

>The length of pregnancy in the rabbit is 31 days and the doe can produce from 1 to 12 young each time she gives birth. She can become pregnant again within a few days of giving birth. However it is not good practice to allow the doe to become pregnant straight after giving birth. It is better to mate the doe when her young (litter) are 4 weeks old so that they are 8 weeks old when the next litter is born. In this way one doe can produce 6 litters a year.

Given she looks about to give birth any moment and is only now bringing it up definitely supports the 31 days part.
