Boiling something won't get rid of proteins, so OP has been drinking particals of cooked menstrual blood in their coffee.

what? do you not wash/clean your coffee pot? ...

but not with period blood.........

Well, there's no telling what the roomie has floating around in her bloodstream. I wouldn't want anybody's bodily secretions in my dishes. That's just gross. That mess is how people end up with hepatitis. If she's putting her moon cup in the coffee maker, there's no telling what else she's up to.

Same here, I have this pot I only use to sterilize my menstrual cup. My roommate still somehow managed to go into my cupboard, take the pot without asking me, and use it to cook pasta. I'm not sure if I should tell them.

I'd have no issues telling my roomie in that situation #16. They need to learn not go through your stuff. And this is the perfect way to do it. You're also being honest with them, so yeah.

Even if it wasn't menstrual blood and it came from a leg or arm, I still would want to be drinking out of it.... it's blood

#16 honestly you should tell them. They will probably freak out at fist but it's their fault. Even if they try your roommate can't get mad at you since they took it without permission. Telling them will deffinatly teach them not to use your things without asking. Heck after you tell them they probably won't even go in your room anymore lol

Same here. What kind of idiot does that?
