HI all...I'm on my 3rd pregnancy. I gained approximately 50 with my dd and 40 with my ds. I'm now almost 19 weeks and have only gained about 2 ibs. I did start off about 15 ibs heavier than my usual weight when I got pregnant. My appetite has been terrible, especially in the first trimester. It's slowly gotten better but since I have to eat gluten free (Celiac) I have such a hard time finding food besides salad, fruit, etc. Anyone ever gain a low amount? Anything I should be concerned about at this point?
