animals and pregnancy!

I'm currently dealing with my 2 year old dog and his weird behavior since finding out I am pregnant. The  past 3 weeks he has been peeing in my house  he literally comes into my room and pees right in front of my husband and I, he has never acted out like this he is let out when he needs to be he's really good at telling us. My cat seems to be doing well with this pregnancy as she is clingy right now! Anyone else experiencing odd behavior with your animals while being pregnant if so how do you deal with it?
