Awww please don't worry about it. People sincerely don't have a clue when they say what they are saying.
I'm big too and this is my first baby. This pic of me was taken at 22 weeks can you believe that I have an anterior placenta and until the other day I hadn't even felt anything!!! How can I be this big and not feel anything
I'm bigger than my friend was when she was full term and I'm getting comments all the time.
Everyone carries differently and as long as you and your baby are healthy then that's what matters. We're not pregnant for a long time so we should be focussing our energies into feeling positive and making sure that that positivity passes through to baby.
You've got a bump because you've got a beautiful child growing inside you and there are lots of people who will be envious of that but they would never say so.
Bumps are mesmerising things because of what they are and what they mean, you will attract attention from strangers, friends and colleagues because being pregnant is just a bizarre, wonderful, natural and 'how the f@&k do we grow human beings inside us' mind bending thought that it just catches everyone's attention.
You cannot change your body or bump and it'll never go away now until after baby is born so try and turn it into a positive than a negative. You look fantastic and you are making a little human being, now that's flippin' amazing
