I don't have a tailbone connected to spine (spina bifida, covered). will this affect my pregnancy?

Sensation of pelvis: The pregnancy should not be a problem. However, problems with sensation of lower pelvis and especially the bladder can be affected. You should check with your ob/gyn to see if there are any more problems with natural labor. Thanks.

Depends: This is surely something that your ob/gyn is aware of. Spina biifida may or may not be associated with symptoms and your OB is most likely to answer your question.
