You think your rabbit may be pregnant and shes not moving from her bed area that much. shes also urinated where she stays?

Count from the day she was bred. If more than 30 days have passed she IS NOT pregnant. There are several things that could explain her behavior. If she has urinated in her nest box you have put her nest box in her 'potty' corner. Try moving it to another corner. If she is spending a lot of time in her nest box there could be several reasons but if it is not cold I would check your rabbit's hocks. It may have sore hocks.
