When does baby bump start to appear? I’ve have two children 12 and 8, but i can not remember at what point a bump starts to show. I know we get bloating etc with all the changes and hormones in early pregnancy but I’m just wondering when a proper little bump emerges. I’m attending a hen do in May and i’m not sure if I’ll need to buy a maternity style dress or if I’ll get away with an existing dress. I’m almost 8 weeks now so I’ll be about 4 months by then.
