You are quite correct in that the majority of "diagnosed" cases of CPD are crapola! I'm not saying it doesn't exist but rather, as Kelly says, unless you have had serious trauma to your pelvis then it's highly unlikely that your body has grown a baby that you "can't" birth.

Oh, and as a health professional in my line of work I see up to 15 pelvises (pelvii?! ) every day and nearly every single one of them is "uneven" to some degree. Even people without back pain/issues have an uneven pelvis.

Yay for you and your perfectly-able body!
