Baby’s Growth and Development
At 17 weeks pregnant, your baby is about the size of a large onion. They are approximately 5.1 inches long and weigh around 5.9 ounces. Your baby is starting to gain more fat, which will help them regulate their body temperature once they are born.

Your baby’s skeleton is also continuing to develop. Their bones are hardening, and their joints are becoming more flexible. This will help your baby move around more easily as they continue to grow.
Your baby’s digestive system is also starting to work. They are swallowing amniotic fluid, which helps their digestive system practice moving food through their intestines. Your baby’s taste buds are also forming, and they can taste different flavors in the amniotic fluid.
Your Body at 17 Weeks Pregnant
At 17 weeks pregnant, you may start to feel more energetic and less nauseous. Your uterus is about the size of a small melon, and you may start to notice a slight bump in your belly. You may also start to feel your baby moving more frequently. These movements may feel like flutters, bubbles, or even small kicks.
As your baby grows, your body will go through many changes. You may notice stretch marks on your belly, breasts, or thighs. Your feet and ankles may also swell, especially if you spend a lot of time on your feet. This is normal and usually nothing to worry about.
What to Expect at Your Prenatal Appointment
At your 17-week prenatal appointment, your healthcare provider may listen to your baby’s heartbeat using a fetal Doppler. They may also measure your belly to make sure your baby is growing appropriately. Your healthcare provider may also discuss any questions or concerns you have and offer guidance on nutrition, exercise, and other aspects of your pregnancy.
Frequently Asked Questions
1. Can I still exercise at 17 weeks pregnant?
Yes! Exercise is important during pregnancy, as it can help you maintain a healthy weight and reduce your risk of complications. Low-impact exercises like swimming, walking, and yoga are usually safe during pregnancy. However, it’s important to talk to your healthcare provider before starting any new exercise program.
2. Is it normal to have stretch marks at 17 weeks pregnant?
Yes, it’s common to develop stretch marks during pregnancy. As your skin stretches to accommodate your growing baby, it may become itchy, dry, or irritated. Using a moisturizer or oil on your belly, breasts, and thighs may help reduce the appearance of stretch marks.
3. When will I start feeling my baby move?
Most women start feeling their baby move between 16 and 22 weeks of pregnancy. These movements may feel like flutters, bubbles, or even small kicks. If you haven’t felt your baby move yet, don’t worry. Every pregnancy is different, and you may just need to wait a little longer.
4. What can I do to ease swelling in my feet and ankles?
Swelling in the feet and ankles is common during pregnancy, especially in the third trimester. To ease swelling, try elevating your feet when you can, wearing comfortable shoes, and avoiding standing or sitting for long periods. Drinking plenty of water and eating a healthy diet may also help.

In most cases, it’s safe to travel during pregnancy. However, you should talk to your healthcare provider before making any travel plans. Depending on your pregnancy and your destination, your healthcare provider may recommend certain precautions or restrictions.
In conclusion, week 17 is an exciting time in your pregnancy. Your baby is growing and developing at a rapid pace, and you may start to feel their movements more frequently.
