Hello doctor, My weight was 51 kg during beginning of my pregnancy.in middle of second trimester my weight was around 52 to 54 kg. Now I checked my weight in middle of trimester I gained upto 59 kg. Now I am in the end of trimester my weight is 60 kg. How is it possible to gain such much weight in short period of time. Even though I take only quantity of food. Is anything I have to do to control my weight or is it common to be like this during pregnancy time. please clear my doubt.
