Especially in the third trimester.
Soldier (female, obviously) has given birth while on duty in Afghanistan. I've never understood how people manage not to know they are pregnant.
I suppose female soldiers on duty might take drugs to stop their periods, which might partly explain why she "wouldn't notice" she wasn't having periods, but there are quite large physical changes during pregnancy. How do people miss these? I've always assumed that such people must be very UNBodyAware. My 'bumps' were quite hard, and I felt lots of trial contractions, then there were breast changes (colostrum not least), and many more telltale signs.
How on earth do they manage NOT TO NOTICE?
