Weight

So we are 15 wks into this pregnancy and I have gained less than 5 lbs the whole time! This is awesome. Its hard to know how much weight I've actually gained due to my fluctuating water retention. But I am thrilled with less than 5 lbs. I know now that I'm into the second trimester I need to watch my weight more carefully. I've started being more hungry so I'm sure this is the time where I could add weight too quickly.
