I weighed 149 pre pregnancy. i'm 5'1" and i'm 23 weeks and now weigh 133. i lost over 20lbs before finally gaining 3lbs in the last 4 months. has anyone else gone through this? i don't have bad morning sickness and i eat the amount i'm supposed to.

It happened to me, i was when this pregnancy started. now i'm 36 weeks and weigh 187.5lb. the dr. said my baby is in good health and weighs 5.6lb. i just happen to lose a few pounds, but that doesn't mean i'm not eating well., every pregnancy is different.

Don't worry you will lose it all soon after the baby is born. i lost 30 lbs within the week the baby was born and then another 20lbs because i breast fed.

My first baby i was 130 and went to 215, with high blood pressure and high diabetes too. all body liquid. i took 1 year to go back to my 130... now i am 30 weeks with my second one. i was 145 and now i am 190, no blood pressure no diabetes, but my body still produced a lot of body liquid. all is normal in the end, we have a beautiful and blessed baby, just be patient. we took 9 months to gain it, we can take 9 or more months to lose it... just be happy and enjoy, if you're stuck in all this you'll never loose it. be careful with depression because it can be in your way to lose the weight.

I have gained 24 pounds in 13 weeks. i've gained nearly 60 lbs, with my other two pregnancies but never this quickly. i swim five days a week but i have been indulging in foods i don't typically eat. i'm really concerned. i have had one baby (at term) that weighed 10lbs. 10 oz. another (3 1/2 weeks early) that weighed 10 lbs. 10 oz. i was in good shape and now i'm struggling.

I'm just concerned. i'm 17 weeks pregnant and starting and current weight is 171 lbs. this tracker says i should be 178 lbs by now. i'm visually bigger, but no weight gain. i'm 5'4 and though it says i'm overweight for size, i'm wondering if i am not gaining weight because of my previous body style. always weighed more, but you can tell by looking at me because i'm extremely athletic and mostly muscle mass (always been on the thicker side too with that said) but i have been this same weight also for years whether i was super "fat" or super toned so maybe it's just my body?? just concerned.

Pre-pregnancy weight was 125-128. fluctuated very often between those two. i'm 5'8". i just entered my 21 weeks yesterday and i weigh 146. i know that my breasts did get much bigger, but i'm worried i'm gaining too much weight, too quickly. i eat relatively healthy and walk/swim/stretch at least 3 times a week. any recommendations, words of wisdom or words of anything in general? :) thank you!

I wouldn't worry. if you feel good and are eating healthy and exercising don't get caught up on the numbers. i gained 45lbs with my first daughter, she was 7lb 15oz and gained 35 with my second daughter and she was 8lbs 14oz. everyone is different and as long as you feel healthy and have a little energy ( what we can being pregnant lol) then don't stress it's bad for you and the baby. i'm 16 weeks and have gained 6lbs so far but i expect to gain about 1-1.5lbs each week from here on out. you're perfect unless your doctor is concerned. congratulations!
