Excess fluid retention at 37 weeks pregnant?

Muscle weighs more than fat. If you have become more active and eating more healthy and do not look any fatter it could be muscle. You could talk to your IB/GYN and then if nothing is wrong you could go to a person that checks your diet and your fat content to see if you are carrying fat or muscle and what you need to do.. good on you for eating healthy. and do exercise after baby is born and stay eating healthy it will come of especially if you feed after. Oops I forgot it is normal to put wight on I think about 10 kilos? any one else confirm this.
