I have been trying to get things organized for the twins' arrival this week...yesterday we went to Lowe's and walked around for an hour, and then came home and cleaned a bit and picked up my daughter's 3000 toys. Well, in the evening I started feeling a weird stretching and pulling sensation all over my belly...nothing that I'd ever felt with my daughter. I'm assuming I overdid it and have spent all day today on the couch with my feet up, but anytime I have gotten up to do anything minor the sensation comes back. I'm going to call my OB tomorrow but wondering if this happened to anyone else this early ( 21 weeks) and what the outcome was?
