It really depends on your starting weight. If you have started your pregnancy at a healthy weight which is normal for your age and height then you are expected to gain between ten to fourteen kilos thru your pregnancy

im 19weeks pregnant...initially my weight was already 71kg ... now im 81... is it ok ?

ideal weight gain in pregnancy should be around 10-12 kg.

it depends on where u started from at the beginning of pregnancy..ideally not more than 300gm/week is what I have heard.
