interestingly there is a (rare) phenomenon where the male partner gets some or all of the menstrual or pregnancy symptoms. Apparently my grandmother could tell she was pregnant (she had 10 total not including miscarriages) because my grandfather would get morning sickness! Partially explains how she managed to have 10 if she wasn't having to deal with all the symptoms herself. As an aside, apparently the local doctor told her it was a shame she'd already had her appendix out because otherwise he could do a prophylactic appendectomy and "accidentally" cut her tubes while he was in there.
