Ok my baby was weighing 4lbs at 30 weeks when dr did ultrasound and measurements....was concerned about her being a big baby and I'm a little person pretty much if I go 40 weeks she will be a 9 lb baby. It's weird bc I don't have gestational diabetes and me and my husband neither of us are big people. I'm petite and only 5'0 and my husband is only 5'9 . Is it possible for me to pass my baby vaginally with no problems if she is 9 lbs and I'm such a small person?! Also is it possible to have a big baby and not have gestational diabetes?! I was worried bc she was measuring so big that they might have made a mistake about my diabetes test?!
