Uterine cast! Yup, there's at least a large handful of people at VP who've had these things, either in strips or -- in one case that, if I recall correctly, left the person fainting with the pain -- an entire uterus "cast." Being on HBC can make people slightly more prone to these, too.

It's almost certainly fine, especially if you have no continuing pain.

(Do you suppose, though, that you could change "ladies" to something a bit more gender-neutral? VP has guys with vaginas as well, many of whom may be on HBC to try to minimize having to deal with their nethers, and who may've had similar issues. Thanks!)
