Conclusion

Welcome to Week 18 of pregnancy, Supermom! Your baby’s lungs are growing with essential structures like bronchioles and respiratory sacs. While you may not feel their movements yet, they’re busy yawning, hiccupping, and practicing other motions. As your body adjusts, you might experience swelling, leg cramps, and backaches. Our Apollo doctors and supportive community are always here to help—keep going strong, Supermom!

FAQs

Is it normal to not feel my baby move at 18 weeks?

Yes, it's normal, especially if this is your first pregnancy. Some women may not feel movements until around 20-22 weeks. If you have any concerns, talk to your doctor.

Is it safe to exercise at 18 weeks pregnant?

Yes, in most cases, exercise is safe and beneficial during pregnancy. Low-impact activities like walking, swimming, and prenatal yoga are excellent choices. However, always consult your doctor before starting or continuing any exercise routine.

What should I eat to support my baby's development at 18 weeks?

Focus on a balanced diet rich in fruits, vegetables, whole grains, lean proteins, omega-3, and healthy fats. Key nutrients include folic acid (found in leafy greens), calcium (from dairy products or fortified foods), and iron (from red meat, beans, or fortified cereals). Avoid high-mercury fish, raw or undercooked meats, excessive sugar, and processed foods.

Is it normal to have back pain at 18 weeks pregnant?

Yes, back pain is a common complaint during pregnancy, especially as your uterus grows and your centre of gravity shifts. Gentle exercises, proper posture, and supportive footwear can help alleviate discomfort. If the pain is severe or persists, consult your doctor.

What should I expect at my 18-week prenatal appointment?

Your doctor will check your weight, blood pressure, and fundal height. They may also listen to your baby's heartbeat and discuss any concerns or questions you have. If you're due for the anomaly scan or maternal serum screening, these tests will be scheduled or performed during this visit.
