baby boy prediction

It was about a week before af was due and I was feeling pms-y and bloated. It's not uncommon for the bloating to make me look pregnant if I'm not watching what I eat. (I often get asked by strangers when I'm due when I'm not actually pregnant - but thats a rant and rave for a whole other post though.) Anyway, I was at a restaurant the other day and instead of asking me if I was pregnant the older man behind the register told me I was having a baby boy. He didn't really speak English and it was far less awkward than my previous encounters about my bloated belly. I was about 8 dpo at the time so not pregnant yet, but my period is 4 days late now and secretly hoping that old man is some wise psychic guru.
