When you are pregnant, your healthcare provider measures your belly to estimate the size of your baby. This measurement is called fundal height. At 38 weeks, it is normal for the measurement to match your gestational age within a few centimeters. However, if you are measuring significantly larger than expected (in this case, 42), it could indicate that your baby is larger than average or that you have excess amniotic fluid (polyhydramnios).
It's important to note that fundal height measurements are not always accurate in determining the exact size of the baby or any potential issues. That's why your healthcare provider has scheduled a growth scan for next week. During the scan, they will take more detailed measurements of your baby's size and assess their overall well-being.
There can be various reasons for an increased fundal height measurement, such as genetics, multiple pregnancies (twins or more), or gestational diabetes. It doesn't necessarily mean there is something wrong with your baby's growth.
During the growth scan, the ultrasound technician will measure different parts of your baby's body to estimate their weight and check if they are growing appropriately for their gestational age. They will also evaluate other factors like amniotic fluid levels and placental function.
Based on the results of the growth scan, your healthcare provider will determine if any further action needs to be taken. If everything looks normal during the scan, it's likely that your baby is just on the larger side or you have extra amniotic fluid, which may not pose any significant risks.
However, if there are concerns about your baby's growth, your healthcare provider may recommend additional tests or interventions. This could include monitoring your blood sugar levels if gestational diabetes is suspected, scheduling more frequent ultrasounds to closely monitor the baby's growth, or discussing the possibility of inducing labor earlier than expected.
It's natural to feel worried or anxious when faced with a measurement that deviates from what you've experienced in previous pregnancies. However, try to stay positive and remember that each pregnancy is unique. The growth scan will provide more accurate information about your baby's size and well-being. In the meantime, if you have any specific concerns or questions, don't hesitate to reach out to your healthcare provider for guidance and reassurance.
