There could be measurement error and you are in week22 and there a long way to labour. My girl was of a heavier weight at early pregnancy and then I was diagnosed with GD at wk24, and then my girl weight increase very slowly (diagnosed of pre eclampsia at wk34). Not trying to scare you, but a lot of things can happen from now to labour. Hence, you do not have to worry now. Try to eat healthy!
