I'm only 12 weeks, and already I feel my muscles seperating in my belly button and right above. True, I had only gotten them to reconnect right before getting pregnant again, but I've been doing ab work religiously, so I didn't think they'd seperate this quickly. Is it just a second pregnancy thing? I'm going to try those crunches where you suck your belly button into your spine, but is it hopeless at this point? Anyone know?
