Hi, I am only 4weeks 1day, but have noticed that I already seem to be getting a bit of a 'bump'. I have to undo the button on my jeans etc when sitting down or driving as its really quite uncomfortable. Is this normal? Did anyone else start to bump this early or is it possible to get water retention when pg? I didnt really suffer from bloating b4 af, and am a size 6-8, so could it be down to that? Any help would be appreciated as I am convinced that I will end up as big as an elephant at this rate!
