Weight gain ladies?

Smilie • Hello our first baby girl is on the way on the 22nd November 2015... Please be a sticky baby 👼 ✨BD to all
Hello touchy question but what's the normal weight gain throughout the whole pregnancy 
And how much weight did you ladies gain in the first 12 weeks. I'm worried I'm not gaining enough on the scales but Iook more fuller in my hips and lower tummy. Thank you 😃
