Answer: Hi dear, I can completely understand your concern as hip pain is one of the most common aches that pregnant women experience. In general, relaxing and other hormones are to blame. They cause relaxation and stretching of your pelvic floor, which also moves your coccyx.Often, what feels like lower back pain and hip pain during pregnancy is actually tailbone pain. If your pain is severe or lasts more than a few days with little change or if it worsens, see your doctor. You’ll need a yoga mat to comfortably perform this stretching routine. Muscles worked: This pelvic tilt moves your spine by using your arm, abdominal, and back muscles. Begin on all fours, with your feet flat (toes not tucked). Keep your shoulders directly over your wrists and hips directly over your knees. As you inhale, drop your belly, letting your back arch but keeping your shoulders rolled back and down. This is Cow. As you exhale, press into your hands and round your upper back. This is Cat. Continue moving on your inhales and exhales. Repeat 10 times.
