I've always thought HD was related to birth position and/or birthing. I've never considered it to be genetic

I guess if I was in the same position as you I'd be researching the likelihood of it occurring again. If genetics played a part or if it is something unfortunate that happens and there is no control over it or if the OB/MW can provide birthing suggestions/techniques to reduce the likelihood of it happening again.

Also, if a Chiro can help after birth.

Suppose these are all hypotheticals for me as I've yet to experience a bfp.
