Expected Fundal Height At 7 Weeks Gestation
Should fundal height match gestational age from lmp? I.E. If 28 weeks from lmp, fundal height should be approx 28 cm
Within 3 wks: This is a rough guideline that obstetricians follow after 20wks. A three week discrepancy is acceptable and if greater, should prompt need for ultrasound evaluation. ...Read more
When your due date arrives, you will be more than ready to have your baby! Most women deliver the baby somewhere between 37 and 42 weeks. According to the American College of Obstetricians and Gynecologists, only 5% of babies arrive on the exact due date. Approximately 7% of babies are not delivered by 42 weeks, and when that happens, it is referred to ...Read more
Should your fundal height measure to gestational age or fetal age? I.E. If 25 weeks from LMP should it be 25cm?
Measuring tape: Use the centimeter side and measure from the middle of the pubic bone (place the zero there) to the top of the curve of the uterus. In general the number of centimeters is about the number of weeks once beyond about 15 weeks. ...Read more
Top of the uterus: Fundal height refers to the location of the top of your uterus. This is a quick and easy way to confirm that the uterus is growing normally. We start at the top of the pubic bone and use the tape measure to locate the top of the uterus. After 20 weeks this distance in centimeters roughly equals your gestational age. Ex: 28 CM fundal height = 28 weeks gestation. ...Read more
None: An 8 week uterus is usually not popping out of the pelvis yet - if you are thin then it may be palpable above the pubic bone. ...Read more
21 weeks: Fundal height is measured from the pubic bone to the top of the uterus. The number in centimeters usually correlates pretty well with the number of weeks of pregnancy. Ultrasound gives a more precise gestational age. Obstetricians measure fundal height regularly to make sure the fetus is growing as expected. ...Read more
20 weeks gestation: In clinical practice, recording the actual fundal height measurement from the palpable top of the uterus to the superior edge of the pubic symphysis is standard practice beginning around 20 weeks gestation. Most caregivers will record their patient's fundal height on every prenatal visit. Measuring the fundal height can be an indicator of proper fetal growth and amniotic fluid development. ...Read more
Fundal height is 4 weeks more than my due date but baby measuring 2 weeks smaller than my due date, what does this mean?
3rd u/s done @ 28w2d, at apt the next day was told growth & fluid were normal but my fundal height measured 33. Dr not concerned, what could this mean?
Probably not much: As long as us looks ok, and all evidence shows baby is healthy and growing, that's good. No test is 100% perfect and there are no 100% guarantees even with 1000s of tests or exams. Ask your doctor next time. Often the weeks gestation and fundal height don't match exactly. Everthing you reported here sounds ok. ...Read more

Diagnosed my baby fetal macrsomia. I'm 33wks+5 and fundal height measuring 37 wks. Ultrasound at 2 wks ahead. Have no risk factors. Should I worry?
Macrosomia: Every baby grows at slightly different rates. U/S measurements are "dated" on an average growth rate, so any given time may be larger or smaller than average, but still be normal. Sometimes, the U/S may be correct, but since bleeding can occur with pregnancy, you may just have gotten pregnant a month earlier than you calculated. ...Read more
What is more accurate? Fundal height measurement or measuring the baby through an ultrasound? I'll be 24w tomorrow and haven't had my belly measured
Baby growth: The fundal height is good for trending over the course of your pregnancy and fh is +/- 2-4 cm = weeks once past 20 weeks. Most doc's will start measuring fh at 20 or 24 week visit. U/s has a 10-15% error of calculating baby weight throughout pregnancy and assigning dates varies with gestational age. ...Read more
I am 36 weeks. Ultrasound showed 6lbs1oz. My fundal height is measuring behind at 35 cm. It's been perfect until now. Is this normal when baby drops?
Yes: Ultrasounds and fundal heights can only "guess" at weights and gestational age unless done serially. Once the baby drops into the pelvis generally at 36 weeks gestation the fundal heights are "iffy". ...Read more
At 10 weeks I measured 14 weeks in fundal height. My bladder was full at the time, how much would that affect how big my uterus measured?
Fundal height? I'm measuring right 18 cms at 18 weeks but I don't understand why the top of my uterus is 2cms above belly button. By charts that's 24week
Not accurate.: Fundal height assessment is "poor man's" ultrasound to assess fetal growth. It is notoriously inaccurate and depends on maternal weight for height, fibroids, amniotic fluid volume, lordosis of the maternal spine and experience of the examining prenatal care provider. I would not read too much into it and rather rely on the ultrasound measurements at any time. ...Read more

If my fundal measures at 17 1/2 CM and im supposed to be 18 and 4 days gestation how is that right?
That is perfect: You are describing a 0.5 cm difference between your measurement and your gestation. Think about how small 0.5 cm is. This is a completely normal measurement. ...Read more
Single intruterine fundal gestational sac is seen with no detectable fetal pole development at 7 weeks 4 days will the baby survive looks like 5weeks?
Less likely: So, the first assumption is that the dating is correct. If you are truly 7+4 weeks, there should be both a fetal pole and a heartbeat. But for various reasons you may be only 5-6 weeks so worth repeating ultrasound to make sure ...Read more
Why is it better to wait until 8 week gestation versus seven weeks gestation in order to have an accurate dating ultrasound?
I have irregular gestational sacs, I am almost seven weeks pregnant with twins. Does this mean I will have a miscarriage?
No: It just means that he gestational sacs are growing and forming at different rates. ...Read more
Currently weighing 207 height 5'7" and about 6wks pregnant... What would be the ideal weight to lose and maintain throughout the pregnancy?
Does pregnancy increase or decrease a teen's final height? If one of 2 identical twin sisters got pregnant at 14 yrs, which twin would end up taller?
Height: The non pregnant twin would be taller. ...Read more
The BMI chart: We only use height and wt to determine healthy vs not-healthy-wt ranges for both men and women. It is a rough estimate and provide you a guide to keep "ideal body wt" for better health. In her case, she is a bit overweight and so she should try not to gain too much during pregnancy--otherwise wt loss is not really needed for pregnancy in her case. Consult doc. Good luck. ...Read more
If you weigh 181 pounds and are 5'4 in height is it possible to start showing at 3 months in pregnancy?
Depends: It depends on your body type and if you have had other pregnancies. At 12 weeks the uterus is at the brim of the pubic bone. Where your doctor can feel it but your tummy may still be relatively flat. If you are "showing" a lot ask your md about the possibility of twins or more! ...Read more
