In this wonderful age, it isn’t difficult to find out if a woman is “in a family way.” These lovely bathroom wands will clear up the question right quick.
But how did they determine pregnancy in previous generations? Did they wait three month, and if there was still no “cycle,” they figured they knew their condition? That’s one option. I understand that there was a procedure involving a rabbit (from what I’ve pieced together from an Aerosmith song and an episode of M*A*S*H*, the poor fellow didn’t survive the procedure). But since not everyone had access to a rabbit, or had to keep their rabbits for breeding and stew, some of our clever ancestors had to develop another method.
If a man suspected that his wife (or other “Lady Friend”) was expecting, he would eat a clove of garlic. After an hour, he would return home. If he opened the door to find the lady in question had a disgusted/mortified look on her face (the look usually reserved for when one farts at her parent’s dinner table, or in Church). If the man was greeted with “Sweet Mother of GOD, You STINK!” the mystery was solved. Time to build, or dust off, the cradle.
