I'm going to apologize in advance for not reading all the replies before answering the OP... Not all women need to gain the same amount of weight during pregnancy. Some of us, like myself, gain lots more than average (and I still had tiny babies). Some don't gain near as much. I'd be seriously looking for a new care-provider if the one you have is giving you greif about how much you weigh. Things like that send up warning flags in my mind. As long as you are healthy and eating a well balanced diet, it shouldn't matter.
