I hope I don't sound odd, but how do you tell the difference between a headbutt, a kick, a punch etc? I feel movements in my pelvic area and I've starting to get what I'd describe as twinges much lower, almost in the cervical region, but I've got no idea what part of the baby's bodies causes the movement. I can often feel a very rounded section or indeed two so I know one must be the head and one must be her bottom but how do you tell what's what? Or am I just thick?!
