Your pregnancy at 21 weeks
Sore spots
Backaches, especially in the lower back, are quite common during pregnancy. Your growing uterus is shifting your center of gravity and pulling your lower back forwards. Meanwhile, the hormone relaxing is loosening every joint and ligament in your body, which will allow your pelvis to expand when it’s time for delivery.
Back Savers
At 21 weeks pregnant, Whenever you sit, whether you're watching television or working, use a footrest to elevate your feet slightly. If you need to stand for a long period of time, alternate putting one foot on a small stool to take some pressure off your lower back. Treat yourself to a warm bath for additional relief. If your back pain continues, give your health care provider a call.
Twin development at week 21
