I'm 15 + 3, first pregnancy and I have quite a big belly already, it has been this way since 11-12 weeks. I thought maybe it's bloating at first, but it never goes down its always the same and just getting bigger. I'm still going to the toilet ok and wasn't overweight to start with and was a size 10. I know the baby is only small still so can't be this big already lol. Everyone keeps saying am I sure I'm only 15, it's making me feel huge! Has anyone else had this?
