On my first pregnancy appointment (5 weeks) I was weighing 121 lbs, I’m currently 126 lbs at 27weeks. I’m constantly eating healthy, not healthy, big, small meals around the clock. This is my third pregnancy, my doctor ( who has seen me since my first pregnancy) is not worried because he knows I have always been on the small size. He checked my fundal height and I’m measuring 27 as well. I’m worried baby is not getting right nutrients and not gaining weight. Has anyone been through this as well? Please help!
