Kind of an embarring question, but I need to ask?

Okay, so all my life (or...at least for the past 7 years since Aunt Flo first visited) I've been using tampons. Now I have some medical issues going on, and my doctor wants me to use pads. Okay sooo here's my question: When Aunt Flo is kinda heavy, what exactly do you do about showering? Mine gets really, really heavy, and I feel like it would...get everywhere. Does the water just wash it away with no problem? And how exactly am I supposed to dry off? Sorry, this is the stupidest and most embarring question I've ever asked in my life (hence why I'm asking it online and not face to face with someone haha).
