In fact is seams that some authors do have that opinion but on pregnancy, and I quote CPA (1), “Houghton et al. (2) indicate that NMES is contraindicated ‘‘anywhere’’ on pregnant women” but CPA also refer that “however, there appears to be no evidence for this”.
On postpartum I can’t find no references to contraindicate NMES.
The CPA document is an excellent reference for this issue.
