L.M.
Mine did the same thing and went back to an innie. You have to remember that there's a lot going on in there and everything has to push outward to make room for the baby. Worry not. The only other advice I have for you is to be consistant about rubbing your belly with vitamin E lotion and/or Mederma through your entire pregnancy! I got lazy and now have more stretch marks than I probably would if I had done it everyday. Enjoy your pregnancy and your baby!
