pregnancy

yesterday my buck and doe were together for a few hours and we’re doing their business for a long time. He obviously finished several times, so I separated them for the night. Today I placed them back together and she turned and started humping him and bit him so I immediately separated them...

I have a doe mini lop that I have rescued from a neglect home. She is pregnant and starting to nest and pull fur. Is there anyway to tell when she is about to give birth? Thanks
