Some people's bodies are more primal than others. your body knows that you need an extra cushion to keep your baby safe and healthy. it's nothing to worry about. you have to remember not only is your baby growing but so are all the organs and fluid in your body. congratulations on your pregnancy! enjoy this time and don't worry about the weight gain. i'm sure you'll have no problem with losing it after your beautiful baby is born.

I'm 5'6" and 161lbs at 37 weeks pregnant. i started off at 126 lbs. this is baby number two. my first just turned a year old in early march. should i be concerned that i am "6 lbs overweight" for what i should be at 37 weeks pregnant?

Just in case there's any bigger girls out there. i started at 277lbs and i'm now 20 weeks and have lost 11lbs. most of this loss happened between week 7 and week 13 where i lost 13lbs mostly due to being off all food. no sickness just constant nausea. i have had no cravings but since week 13 i have put back on 2lbs. none of this is planned i've just tried to make sure i drink a lot of water and eat 3 normal varied meals. except for one occasion where i ate a share pack of popcorn for dinner by myself. not my proudest moment but mmm popcorn haha.

Mmm hmm.

Guest Apr 21, 2017 01:48:34 PM ET

You're okay, as long as you are seeing your doctor, eating and taking you prenatal vitamins, your baby is getting what it needs. i'm 31 weeks, 5'3, started at 130, and am now 139, with my 3rd baby.

guest Apr 25, 2017 10:43:21 PM ET

How do you gain so little weight? do you eat? i need to watch so i don't gain more than 30 pounds, and i started off at 165 at 5'7".

Guest May 6, 2017 03:49:10 AM ET

I am almost 14 weeks and started out 190 and at first i wasn't gaining much weight, i had finally gained a couple pounds then i went down a pound from what i started, and now i am up to 191, but still my weight will go down a little and then back up, which can be normal especially in the first trimester. this is my 5th baby, i gained quite a bit of weight with all my other kids, but wasn't this big before pregnancy, so i'm hoping to stay on track with this one.

Sarah Apr 5, 2017 11:30:13 AM ET

I gained alot of weight with my first pregnancy, about 15 lbs. with my second, and lost a bunch of weight with my 3rd. my 3rd pregnancy my weight was already elevated at 180, after he was born i dropped down to 140 lbs. this is my 4th pregnancy. i am 22 wks and have already gained 15 pounds. i think it can be pretty normal to gain less weight if you are already heavier then your average body weight.

Cassandra Apr 6, 2017 05:27:25 PM ET

What do you mean "finally" gained. you don't need to gain any.

I'm heavy to start off getting pregnant 165. im now 177 at 28 weeks. my doctor hasn't said anything about gaining more weight. am i still ok?

Guest Apr 17, 2017 04:11:00 PM ET

As long as the baby is growing you are fine. i'm 38 weeks and have only gained 12 pounds my whole pregnancy. i actually lost 6 lbs without trying within the last 2 weeks. during my 1st trimester i lost 16 lbs. according to my ultrasound my baby is 6.5 lbs and has been growing steadily. my dr isn't concerned at all.

Guest Apr 23, 2017 11:08:13 AM ET

I don't know exactly how much i weighed when i got pregnant, but i usually fluctuated between 160 an 165. at 9 weeks, i weighed 170; so i'm using 165 as my starting weight. i've never really considered 165 to be *that* heavy as it's considered an average bmi for my height, and i know i'm fairly active. now, at 25 weeks, i weigh 171. since i know that 165 is slightly on the heavy side of an average bmi, i'm not really concerned about my lack of weight gain. i know i'm eating a good diet for the most part and no doctor has expressed any concern over the weight nor has mentioned that the baby isn't getting enough. make healthy food choices, get some mild exercise every day, and talk to your doctor if you're worried, but if you're describing yourself as heavy, then i think your weight gain sounds perfect!
