My baby is measuring 4-weeks-behind: Advice?

My baby measures almost four weeks behind. I’m 15 ish weeks today, but the ultrasound yesterday said they only measure to be 10w5d. That’s impossible because I know when I ovulated. I know when I got pregnant. Even by my last period, I should be 14 weeks minimum. Has this ever happened to you, and what was the cause. I’m really worried. I have three boys and they all measure on time or more significant I’ve never had one so small…


I done this with this pregnancy as well! Now at 31 weeks and 5 days she’s the size she needs to be. No need to worry yet. She may catch up or she may just be a small baby

I wouldn’t worry too much about it, all babies are different. My son was a bit behind until the last two months before birth, then more than made up for it.

Similar situation with my last two pregnancies… my babies always measured smaller… I was induced at 37 weeks and had healthy happy babies… they were just smaller!

I had this with my pregnancy. I had placenta previa and my placenta started to not work right so they had to do an emergency C-section when I was 27 weeks 6 days

Some times baby’s can just be small. So as long as there isn’t anything medically wrong, than don’t worry too much. Baby has time to catch up!

All of my girls measured behind, all of my girls were born under 6lbs even my now 3 year old who was 40 wks and 3 days my son was 7lbs, Maybe baby is a girl :purple_heart::purple_heart::purple_heart:

Measurements taken before baby is born are not always accurate. They told my mom I was gonna be 2-3 lbs and super small and I was gonna be in the NICU. I came out at 7.6lbs and was perfectly healthy.


My 5th was 4-6 weeks behind in growth but she was fine at 20w. She was diagnosed with IUGR, inter uterine growth restriction by 32w. I has weekly ultrasounds to keep an eye on the placenta to make sure baby was getting everything she needed. Hopefully catching it that early they can keep an eye on baby and the placenta to make sure everything is going good outside of the size of baby. I was induced early in fear the placenta would go bad or abrupt.

Based on my last period, I was supposed to be 3 months along. I was only 7 weeks pregnant. Your last period isnt always the best way to tell


I had IUGR with my son & he measured small , had to have tons of ultrasounds. He was born perfect , just on the smaller side.

If the doctor hasn’t voiced his/her concern I wouldn’t worry about it. They go through a huge growth spurt the last couple months

My baby measured a week behind at our first ultrasound but now she’s measuring exactly where she should be and is actually a bit on the big side. As long as your OB isn’t worried, I’d try not to worry too much about it.

I wouldn worry and if the ultrasound sound say it. Then trust it…i knew when my last pd was when i ovulated evt amd i ended up measuring a week behind…sometimes it just happens…

They look at more than size in these early scans. There’s a huge difference developmentally between a 15 week fetus and a 10 week fetus. Either you’re off on when you got pregnant by a month, or something is wrong.

I was told with my last daughter, she is now 23, that I was measuring way to small. She was gonna be 7 pounds or smaller. Nope was a whopping almost 10 pounds. Lol


My second measured 3 weeks behind. Its just an estimate. The measure bones and weight but its never 100% accurate

My first child came 6 weeks late. No mistakr on when I hot pregnant

With my 3rd baby she was measuring small they sent me to mfm for high risk they did ultrasound every two weeks then every week till I had her she was a perfect healthy 6lb baby now my 4th my son was measuring 5 weeks ahead and I new for sure when i got pregnant cause it was the only time we didn’t use a condom and they took him 2 weeks early cause she said he was in 96 percentile range and was just a big boy he was born 8lb9oz and if I would of went to term dr said he would of been a little over 10lb

I would not worry to much baby will be fine some just smaller some are bigger
