I'm about 11 weeks ish, and notice im a little podgier but wouldn't call it a bump yet, when did you notice yours?
I showed with Darla when I was about seven months. I had a little sticky out bit for ages and all of a sudden it literally just appeared. I got real big real fast, but that was right after I stopped smoking, which was around 7 months.
This time I'm 20 weeks and still only have the little pudge. Everyone's different though and it depends greatly on your natural shape.
I was in maternity clothes after 3 months because I was tiny before I had my first but got absolutely huge when I was pregnant
as I am over weight I didnt show for ages. At 36 weeks my mum suddenly said YOU LOOK PREGNANT!!! so I didnt really show until near the end
