My ob says that weight gain is a totally personal thing and someone saying that you are not putting on enough weight or that you are putting on too much weight is nonsense.

The best person to advise regarding weight gain is your health provider who will monitor you from early pregnancy right through to the birth (and so on). They know how much you weighed early pregnancy and your body type so can advise on your personal weight fluctuations.

So, as you say, there is no such thing as "normal" in pregnancy!!

Best wishes - hope this helps
