I’m not a mom, nor have I been pregnant, but if you’re worried that you aren’t eating enough, why not try tracking your intake for a couple of weeks? MyFitnessPal is awesome, and you can get a cheap food scale on Amazon. Figure out how many calories per day you need based on your pregnancy and exercise level, and set that as your goal. You may find that you’re hitting all your targets, and this is just how your body is coping with pregnancy. Or, you may find that you’re not quite getting enough, and throw in an extra yogurt or apple each day. It’ll also come in handy for post-baby…it tracks macros, calories for if/when you want to think about losing weight, extra calories if you breastfeed, etc. 

I seriously love MFP!

Breath, eat a snack, watch some trash TV. You’re fine.

It sounds like you are fine! With my first pregnancy, I lost ~2 lb in the first trimester due to food aversions or just increased metabolism? I didn’t have nausea. It took til 17 or 18 weeks to get back up to my ‘normal’ weight, and I gained about 23 lb total by 39 weeks (gave birth at 39+2). I mentioned it to my doctor a couple times and she was never concerned, said people gain at their own rate and as long as the baby seems okay it should be fine. I didn’t really show at all (besides bloating) until about 23 weeks.

greywacke :  I am 32 weeks and I have just now gained 15 pounds. I actually lost in my first tri, and didnt really start to gain until 20 weeks. As long as baby is measuring fine, I wouldnt worry!

Weight gain is not indicative of a healthy baby. I gained 4.4 kgs total while pregnant and my baby weighed 3.73 kgs. I started out at 60 kgs. I barely looked pregnant until 28 weeks. If baby is growing well, that’s what you look at.

My friend hardly gained any weight in pregnancy, and actually lost two dress sizes.  Her baby was 9 pounds.  She didn’t show until the third trimester  Meanwhile, I’m over here at 28 weeks with my second and already up 30 pounds.  People have told me I was showing since before I got a positive pregnancy test lol.  (Is that even possible?  I think theyre hallucinating.)  With my first, I gained 30 pounds total, and showed in the 16-20 week range.  My baby was just under 6 pounds and may or may not have been growth restricted.  I think a lot if it is just how your hormones happen to affect you.  I easily lost all my baby weight while breastfeeding, and then instantly gained 15 pounds the week I stopped.  Oh well.

If what the rest of us said doesn’t calm your mind, the fact that your OB didn’t mention anything at your weigh-in (which I assume is happening each time you visit!) means it’s all good! The baby is very good at taking what it needs from the mother. If you feel good, there is no need to worry.

I have lost 15lbs this pregnancy so far (12 weeks), from 150lbs to 135 lbs. I brought up the fact to my OB that many women online have put on 5-15lbs so far, and she told me that 10+ is far too much to be putting on in the first trimester if you have not lost any weight. She does want me to put the weight back on that I have lost so far, plus another 15-20 by the end of my pregnancy.

Agree with others- you started out towards the higher end of the BMI range and are gaining on track. I began this pregnancy (my second) at 123lbs at 5’2, didn’t show until 20 weeks (could still hide it at 28 weeks actually) and barely gained weight until well into the second trimester. Now at 39 weeks I have only gained 24lbs total. You are well within the range of normal.

Also, at this stage IUGR is not an issue because the baby doesn’t comrpise any of your weight gain. In a few months from now it will weigh all of one pound, but it’s not contributing to how much or little you weigh now. That weight is comrpised of increased blood, water weight, etc. Good luck!!

Pregnancy weight gain is weird. When I am not pregnant, I’m naturally thin (5’11”, 135 lbs) and can’t gain wait even if I eat like trash. When pregnant, I PACK on the weight. Seriously, even though I really don’t eat much more, it’s like my metabolism just screeches to a halt. 

If your doctor isn’t worried, you shouldn’t be!

I’m nearly 17 weeks and have lost 3 lbs so far. My OB is not concerned, as baby is growing right on track, and this happened with my first pregnancy as well. I don’t think I gained a single pound til 19(?) weeks, then put on 30 during the second half of my pregnancy. At the time she just wanted to be sure I still had an appetite/could keep down food, and that I wasn’t working out excessively – neither of which were the case for me. 

Don’t stress mama! You’re doing a good job 🙂

140 pounds and 5’3” is not really a healthy starting weight. You were literally less than a half pound away from a 25 BMI which is overweight.  Often overweight women gain less during pregnancy because they already have the fat stores leaner women need to build up. 

 

I had gained 5 or 6 pounds by 16 weeks during my first pregnancy but I started from a much lower BMI. Most FTM’s don’t have a bump until 20-24 weeks. Many are so sick during their first trimester that they lose weight. I gained the most weight from like 25-35ish weeks. Also pregnancy weight gain is weird. I would stay the same for two weeks and the gain 4 pounds overnight. 

 

I wouldn’t worry about your low gain so far (and DEF no need to worry about IUGR at 16 weeks!) but I would talk to your doctor about what a healthy weight gain goal is for you because they will probably want you to gain in the 20-25 pound range over your whole pregnancy vs the 25-35 pounds recommended for healthy BMI women.

 

Wishing you a healthy pregnancy!

dgirl715 :  Seriously? OP has a 24.8 BMI. 18-24.9 is considered perfectly healthy. It doesn’t matter if she’s at the top end of normal/healthy, it’s within the range. Beyond that, BMI is more and more frequently being regarded to some level as junk science, because someone who lifts weights and does yoga and comes in at a 25.1 is going to be much better off than someone who eats 1200 calories of junk food a day and comes in at 24.0.

 I was usually 128-130, 5’4″ also and at 16w, i was 131.5 lbs.  And everything was totally normal the entire preg. Bt the time i delivered,  i was 155 or 158 and he was born 8.8 lbs.  I was just all belly, and then by 6 weeks pp i was back to my usual weight and in my pre preg jeans.  So sounds like you’re doing fine to me!

dianaj17 :  Seriously. She said in her OP that she had gained 10 pounds over the last year from eating and isn’t exercising. I know BMI isn’t perfect but if 141.5 is “overweight” and you’ve just gained 10 pounds to land at 140 (pre-Preg), she was going to be “overweight” in another month or two with no change in eating or exercise habits. The BMI ranges exist at encompass different builds, body types, and bone structures. I’m not trying to fat shame, but really? 140 is “healthy” and 141.5 is “overweight”. That’s living right on the edge there.
