Weird crack

Naj

So this is going to sound really weird and daft, but I'm currently 26+4 so the baby is moving all over my belly. I just bent forward to pick something up and felt/heard a gentle crack sound on my right rib. I'm so paranoid that I've done some damage to my babys limbs or something like that, say if the baby was casually resting a toe there. I am a worrier so can someone please advise me?
