That's Pregnancy Induced Tourette's Syndrome, or just "Pregnancy Tourette's," a term my wife coined to describe the sudden outbursts of sailor-intimidating profanity she is prone to these days, inspired by the nausea, indigestion, and general discomfort that are her constant friends.
She's at 18 weeks, well into her second trimester. We've been told these are the halcyon days of pregnancy, when morning sickness abates and before the awkwardness of late term zeppelinitis.
My response to those who seek to encourage us with this hope? Well, I think my wife's P.I.T.S. speaks for both of us.
