I am currently 19 weeks with DC3 and just feeling a bit fed up of comments about how big I am! I have to agree that my bump isn't exactly small, and I've seen pics of a friend on Facebook who is due a few weeks ahead of me but looks tiny still (admittedly she is very slim anyway), but do people have to keep telling me I am big?!
I am size 10-12 and was around 9 and a half stone pre pregnancy. Weighed myself today and I was 10 stone 5, so have put on quite a bit of weight. I think most of it is bump though rather than all over (hard to tell when you're in maternity jeans etc rather than normal clothes...). I was so nauseous in the 1st trimester but found I just wanted to eat through the sickness, it was the only thing that helped, so now I'm paranoid I have piled on way too much and am going to end up ginormous come September when I am due!
I do tend to make quite big babies (DS1 was 8lb 11oz and DS2 was 7lb 1oz but was born at 36+5!) so am probably not destined to have a tiny neat bump, and I don't necessarily believe this is the ultimate objective in pregnancy anyway, but it just makes me feel a bit down getting so many comments about being big.
