I've got you ladies beat by a long shot! I'm up 14 lbs at 16 weeks.
But it's no big deal- this is my fourth pregnancy and this is very normal for me. I gain the bulk of my weight in the beginning and not much in the end, never going over a total of 32ish lbs. I'm typically a small girl that doesn't have a huge appetite, but when I'm pregnant, it kicks into overdrive and my body stores up every bit of that fat as it can!
Other than weight gain, I'm feeling alright physically. Mentally, however, this pregnancy has been HARD. I have had the worst time with my temper, being impatient, and serious lack of motivation to do nearly anything at all. That's been the the most difficult for me. I didn't have this during my last two pregnancies, so I feel very out of whack in that manner. No fun!
