Input: Text: sorry it's my first post on reddit, excuse the poor grammar,  been a lurker for 2 years. 
am an intern sonographer at this health clinic and towards the end of the obstetrics ultrasound scan the expectant mum asks the kids sex..i comb through the perineum of the fetus with no luck but just as am about to throw in the towel and admit that i can't ascertain the fetal sex, i spot two breast like masses around the fetal butt(balls to me).gold. it's a boy ma'am.
five minutes later she's at the waiting room telling whoever cared the good news and i head back to the imaging room where i scroll leisurely through the scan images cine loop only to see two goddamn pawpaws (labia). 
she's giving birth in 2-4 weeks at the same clinic, am in shit.

TIFU by calling labia balls
