firstly welcome to the forum
second, did you intend to breed them?
How old are they both?
Is there any reason why you have not had them spayed/neutered/fixed?
It is very stressful for a female bun to have babies if your female is not a young bunny I would have her spayed asap then she will not get pregnant. if she is young and you are prepared to risk it then you can have her have the babies if she is pregnant but you have to be prepared for a lot of work, there are so many possible complications and worries when doing this.
The reason I suggested having them spayed other than the obvious so the female dsnt get pregnant is because it is good for them and good for their health it helps them and its really important that you do it. Female buns can get cancer if it is not done and it helps males feel lest frustrated and hormonal.
good luck with your buns :wave:
