Pregnancy, Whats Happening in Week Eighteen?
Week eighteen of pregnancy might mean that it’s time for a second trimester ultrasound, which can give the mother-to-be a glimpse at her growing baby. It may be possible to learn the sex of the baby during an ultrasound this week. However, some babies might hide their genitalia, making it impossible to determine the gender. The second trimester ultrasound is important to screen for any potential birth defects, abnormalities, or complications. During week eighteen, the baby begins to flex his or her arms and legs. This movement should become noticeable over the next few weeks, if it has not already. Through the thin skin, blood vessels are now visible. The nerves are covered in myelin sheaths to protect them. Weighing nearly seven ounces, the baby measures in at about five and one half inches long. Moms-to-be may experience an increase in appetite this week. In addition, blood pressure may be lower than normal. This can lead to dizziness, so women should be sure to get up slowly. Pregna
