Menstruation is part of who I am. At a few days away from being 30, I've been menstruating for over half my life. And I'm used to it. I accept the cramps, the bloating, and the high cost of feminine hygiene products. I'm confident I can handle my period on planes, in meetings, and even on beach vacations. I am a seasoned menstruator who always has spare pads in her handbag, in case you ever need to borrow any. And yet, I am freaking terrified of getting my period on my wedding day.
