I'm six weeks post partum and I've noticed lately that when I'm standing up and I rock side to side with the baby in my arms, I have a popping sensation in my hips and pelvis. It doesn't hurt, it's just uncomfortable. And it doesn't do it just once. It does it everytime I rock back and forth.
everything kinda moves and changes when you are pregnant/ have a baby. I would recommend seeing a chiro as soon as you are able. I didn't go much regularly, and now my DD is 16 months and I am almost 11 weeks pregnant and having HORRIBLE back/hip/leg pain. My chiro says it probably started so early because it was a lingering issue with my pelvis from previous pregnancy.
