I am running 33 week of pregnancy but my waight is not growing up! But why? 

If your gyno have advised you that.. everything is normal. Then no need to worry. Usually weight gain will be more in last two months. Baby also grows very fast at that time. So eat healthy and stay relaxed. Have lot of water.

Has your gyneac advised anything? Is she concerned?

gyno said that you are absolutely ok and the lill master is supub. but I am tensed. because its myy first tarm.
