I am over weight and you'd think being pregnant would make me fatter but it's made me lose weight. I'm also an hyperchondriac and think that there is always something wrong but now I'm 32weeks and I've realized after staying up late nights reading things and every pregnancy is different. Don't stress it too much. Just stick with the positive with your baby. That's what's best for you and your baby.
I only gained 2lbs my whole pregnancy. My daughter weighed 7lbs 10.8oz
Dont worry i turned 32 weeks on thursday and my first 3 ½ months of pregnancy i had bad morning sickness i lost 18 pounds does months and was "under weight" then EVERY MONTH after that i gained 2 lb still was "under weight" but my doc was okay with it....a month ago i started having my appointments every 2 WEEKS and started gaining 4lb ...i was 188 before i got pregnant and now i weigh 192.4 sooooo if this makes sense i basically have gained 4 pounds my whole pregnancy if it wasnt for morning sickness
