I am not able to walk properly, as i feel to heavy to walk. Is this normal?

Trouble walking during pregnancy is nothing new. It’s a symptom of pelvic girdle pain or PGP, a pregnancy discomfort. During pregnancy, the growing baby causes a woman’s center of gravity and posture to change. This, along with pregnancy hormones, can cause the pelvic joints to become unstable leading to a variety of mobility issues ranging from minor discomfort to significant pain and sometimes the inability to walk. So it is completely normal
