I was the same way till about almost 7mths...hide it until almost 6mths...125lbs prepregnancy and not 2 long later the thunder hit...I'm big as hell...have gained 38 lbs n like 2 1\2mths...b thankful ..lol...don't worry the weight is coming unless your 1 of the lucky ones
As long as your Dr says everything is fine.. you're fine. I've only gained 13 and I'm nearly 28 weeks
I'm almost five months and have only gained seven. Is because of all the morning sickness I had during the first trimester.
