It is common for healthcare providers to adjust due dates based on various factors, such as ultrasound measurements. Every pregnancy is different, and growth rates can vary. If you have concerns about your size or the changes in your due date, it is important to discuss them with your healthcare provider. They can provide reassurance and guidance based on your specific situation. Additionally, maintaining a healthy lifestyle with proper nutrition and regular prenatal check-ups can support optimal fetal growth. Remember that every woman's body is unique, and it's normal for pregnancies to progress differently. Trusting in the expertise of your healthcare provider will help ensure a healthy pregnancy journey for both you and your baby.
