I'm 31+2 today, wasn't overweight or big before pregnant so my skin isn't too used to stretching like this, but I'm on target for my bump etc and I only have one stretch mark that's about a centimetre long, and no signs of others... is this normal? When did people generally have their bigger ones start becoming noticeable? I've checked and there isn't signs of any more coming just yet, maybe I'm lucky or is this normal and then by next week it'll be like BAM, I'm a tiger?
Also, my belly button is an innie but it feels like it's about to pop out at any point- is this normal?!
