Jealousy?

Ever since I became pregnant I get very jealous of our dog. It is up my SOs butt all the time and VERY clingy to him. It has to sleep in the bed and right between us and anytime I try and move him he growls at me. He will only sleep next to my SO so if I put him on the other side of him so I can try and cuddle my SO turns over and cuddles with the dog. Which means I don't get any cuddles or love at night and no sex with the dog right there constantly. It's starting to really hurt my feelings I've tried talking to my SO about it but he just thinks I'm being dumb. Do you think I'm over reacting?
