28 wks pregnant, gained 6 pounds in 2 wks !?!?!?

Its very normal to gain that much weight in 4 months...You are retaining more nutrients and water for your baby and your baby is also gaining weight. There is nothing wrong with having to take the 3 hour test, they are just wanting to rule out diabetes, lots of women who are pregnant go through the 3 hour test only to find out the surprise, they dont have diabetes. Try not to worry, I know it is very hard. as long as you are healthy and the baby is healthy you are ok. Enjoy your pregnancy, you are about to bring a beautiful life into the world.
