You text/speak in acronyms, like ewcm and af, to your partner, and expect them to understand this gibberish!
You pee in a cup, more than you do in the toilet lol
Although you want morning sex your partner is not allowed to touch you until you've done your temperature.
But if/ when she does arrive you do the opposite and by in bulk, because you're NEVER getting pregnant! LolYou run out of tampax/pads and refuse to buy a new box until AF shows because you're sure you won't be needing them.
