Pregnancy weight gain ๐Ÿ˜‘

Sara
I'm 31 weeks and 15 lbs up, I started at a healthy 10.4 and I am now 11.5 ( I'm 5ft6 ) 
I started showing about 28 weeks and I haven't over thought my weight gain, I get on the scales about once a month, and did so this morning to find I'd gained 1.5lb in 2 weeks. 
However I am getting sick to death of family and friends telling me to throw my pre pregnancy clothes away because I'll never fit into anything again, and then telling me watch what I eat, and then telling me I'm too small and not big enough ! 
it's completely frustrating as I used to be overweight (13 stone) about 4 years ago when I broke my pelvis and laid up and I was very self conscious at that time. 
I'm eating healthily and am not shy a donuts or two ๐Ÿ˜ณ
But I'm very active. What do you all think? 
Has anyone made similar comments? 
I'm trying my hardest not to bite people's heads off when it's brought up
