Quick Overview:

Week 20 marks the halfway point of pregnancy, when a baby girl's ovaries already contain around 7 million eggs and a baby boy's testicles have descended from the abdomen to the scrotum — milestones most parents don't expect to reach so soon. An Anatomy Survey Scan, recommended between 18 and 22 weeks, offers the clearest picture yet of fetal development, while first fetal movements may also begin this week. Common maternal symptoms at this stage include increased vaginal discharge, heartburn, shortness of breath, leg cramps, and occasional dizziness, alongside welcome changes such as higher energy, stronger libido, and thicker hair. Cantaloupe melon is highlighted as a particularly beneficial food at this stage, supplying 19 vitamins and minerals — including folic acid to help prevent neural tube defects, Vitamin C to support immunity, and potassium to regulate fluid balance and blood pressure.
