The issue is that it's really the only medical issue that the Navy is basically saying to the CO, "Ok, we trust your judgment in this medical issue over the FS." If they're going to do it with pregnancy, if I go med down with a sinus infection, should the CO say when he thinks my sinuses have cleared? I get that in the end it's always the CO's decision, but there is significant potential for abuse with the current policy.
100% of the women I have known who have had babies had trouble managing their emotions and seem to lose their marbles rather quickly. Let the skipper decide if he trusts you.
Potential for abuse how?
