It is completely normal for women to show differently during pregnancy, especially if it's their second or subsequent pregnancy. At 17 weeks, some women may have a prominent baby bump while others may not show much at all. Factors such as the position of the uterus, abdominal muscle tone, body shape, and previous pregnancies can all contribute to the variation in how a woman carries her baby.
In your case, since this is your second pregnancy after a gap of 10 years, it's possible that your abdominal muscles are more relaxed compared to your first pregnancy. This can result in less pronounced baby bump and make your abdomen appear more like regular belly fat and rolls.
It's important to remember that every woman's body is unique and there is no "normal" when it comes to how a pregnant belly should look. As long as you are receiving regular prenatal care and your healthcare provider has confirmed that everything looks healthy during check-ups, there is usually no cause for concern.
If you are still worried about the lack of a visible baby bump or have any other concerns about your pregnancy, it's always best to reach out to your healthcare provider. They can provide reassurance based on your specific circumstances and address any questions or worries you may have.
