You are now 5 months pregnant. Your bump is getting bigger. This means that your baby has started to gain weight. As the baby’s sense of taste develops, he will taste whatever you eat, so pay special attention to your diet. At 17 weeks, your baby’s organ systems become functional. She has begun to use and develop her lungs by inhaling and exhaling the amniotic fluid in which she is immersed.
At this stage, expectant mothers should have a quad test and a detailed ultrasound scan. A quad test determines the risk of chromosomal abnormalities, such as Down’s Syndrome. A detailed ultrasound is performed by a doctor to check and monitor the baby’s health and development.
