I was told the same thing and I was also worried. As it turns out, my doctor said that my ab muscles were just very strong from years of working out before pregnancy (and believe me, I've never had a six-pack!). The Ultrasound should indicate the baby's growth. It might just be that your abs are tough and holding everything in nicely. It should also make for an easy recovery after delivery and you'll be back to your pre-pregnancy bod!!
I was the same way with my first. The doctor did a couple extra ultrasounds but my little one was just staying very low and head down which was causing my bump not to measure as big as it should. He was born healthy and happy and was 7 pounds 1.5 ounces.
I was measuring small with my two pregnancies, I'm tiny myself. Both of my pregnancies I had average size babies. Don't worry about it, your just slender frame
I have that problem... I'm 38&1 yesterdays growth the baby was 6lbs 3oz. Gaining one pound every 2 weeks, which is good. As long as the baby is gaining weight it's a good thing. I look at it like... Who wants to have a 8 pound baby? My 1st was 6lbs 14oz she was full 40 weeks, this one I'm being induced at 39&1 . If the baby does not gain weight while in gestation, they will induce you early if the 'womb is not viable ' just means the baby will gain more outside, again not a horrible thing a friend of mine just had this happen baby was 5lbs 8oz and she came home with her in normal time. No worries! Good luck!
But I'm really tiny I was 95 pounds when I got pregnant I'm now starting to gain
Depends. You might just have a small baby. There could be an issue. The only person who can confirm this is your dr.
