Pregnancy weight gain.

No
So I had a appointmet today, my last ultrasound . 
It showed that the baby weights 4lb & 12oz (2.1 kg) . I'm 33 weeks , gonna be 34 on Friday. When I told my MIL she's like how the baby is weak and the food I eat isn't hitting baby, it's hitting me that's why she's weak... But my ultrasound doc said she's the perfect weight according to how many weeks she is. I gain about 35 lbs already. I'm 7 lbs away from 200lbs 😢 is the weight really hitting me? Am I going to end up really fat after birth? 😒
