During this week, the weight growth of the fetus actually slows a bit. Your baby continues to grow, but more attention is paid to internal organs and development than weight gain. Length does not slow as rapidly, so the fetus may take on an extremely thin façade for a while. Male fetuses begin to drop the testes during week 21. The testes will move from inside the body into the scrotal sac. Heart growth and strength is the major focus.
Tips for this week
Eat well, drink well and live well. This is the brightest and most comfortable time in pregnancy so take advantage of these next few weeks of comfort. There are no routine medical tests or appointments required during the 21st week. Most often, all testing (for now) is done so you can enjoy pregnancy.
