i dont know if it's just my experiences, but i am always wary about saying congratulations to somebdy just for having sex. I would be the first (well metaphorically of course) to congratulte them when they actuall have the baby, but not for being 3 months pregnant
the family history research I've been doing shows that my ancestors have been having remarkably early first children since 1670. Perhaps premature birth is genetic.
I'm sorry to disillusion you, Jordy, but these days it seems that people live together outside matrimony until they decide that they want to have a baby together. Completely shocking, I know. You'll be better after a sit-down and a cold drink (half a bottle of Prosecco shgould do it). :)
