I'm 20 wks and weighing myself about every 3 wks at the moment; 5'5" and normal weight is 9 stone so reasonably slim. Bit shocked to find out I have put on 6 lbs in 3 weeks so 11 lbs in total. I know my baby has had a recent growth spurt but wow! I'm not too worried (although hoping I don't get massive!), just wondering what other peoples weight gain was like at this stage...
