I had asked my doctor and he said that there was no medical reasoning for it but he knows that it is normal and does not mean that anything bad is going on. Nothing to worry about my dear.
Oh ya ive felt it with my baby too when she moves occasionally...but for like ur hips and stuff, i heard they start widening and preparing
For the baby to come out. I constantly crack there when i get up and stuff
I would trying that might be really hard to diagnose in utero because of the fact the baby's bones are still hardening.
I've noticed mine comes from the top of my bump when baby kicks i can be laying in bed a she kicks around and it sounds as if her joints are clicking my hubby hears them also and it's obvious it's the baby not me. I'm talking to my midwife about it as i Googled and read on a midwifes forum that a patient had the same and when baby was born it had hip displacia or something like that which ultrasounds can't see :)
It's the hormones that relax your muscles during pregnancy. You will find a lot of things crack and pop on you. It's a normal way for your body to loosen up gradually in preparation for childbirth.
I hear them around my tummy / hip area. They aren't painful though
