Im 33 weeks pregnant. I had to let my moms puppy out of the kennel to go use the bathroom. Well i let her out and she immediately starts chewing on the other dog so i got her away from that then she sees one of our cats and starts biting on her so i went to get the puppy and ended up having to chase it all over the backyard and now my lower side hurts kind of like a pulled nuscle but at the same time its like a cramp. Any advice
