Hi friends, l used to tuck in my tummy while walking. But just of recent, l find it so hard to do so again. Could be pregancy, as l also have other symptoms, including lower back ache, breast soreness. Though am about to be due for my monthly period. What do you guess it could be. Has any has these experiences?
