hmm i had one early last year where i was three weeks late... i'd been regular for about a year (ie, on or around the same date every month), so this absolutely scared the shit out of me and my boyfriend! twasn't a fun time. kept putting off buying a pregnancy test etc...
no idea how my periods went so out of whack (wasn't exactly under stress or anything), because they were irregular for a while after that.
haha when my mum was pregnant with my little sis (i was in kindy)... we were all sitting at my uncle's restaurant having dinner with chefs, waiters and other family members, when i asked her "where do babies come from?"
i think she just mumbled something about eating a lot hahah oh dear.. must've been so embarrassing for her
