Today at work I had this strange and odd pain that came from no where. It was from my belly button down to my lower abdomen. Pretty much the ending of my baby bump. Then the pain moved to my side. It was brief and it didn't really hurt, just surprised me. Everyone thought the baby kicked, but I'm having some doubts. Since this is my first pregnancy, I just wanted to make sure. Is this my baby kicking or is this just a pain from picking up toddlers all day at work? (I'm currently 17 weeks)
