Probably a silly post for some... :-P

This is our first pregnancy and we are excited and nervous all at the same time. Lol! Any who, my pup has been super clingy as of late. She is around 8 years old (not exactly sure since she was a rescue) and has always been an attached and snuggly lap dog. Now she is a bit crazy. When I sit to eat at the table she wants to jump up (not allowed) and she has NEVER been that way. If I leave the room and she didn't notice she frantically looks for me. Could it be she can sense my emotions? I'm only 4 weeks so it couldn't possibly be she senses the little nugget yet. Anyone else out there experience something similar ?
