Dean

Whenever you are on your period, Dean usually leaves for the week to go on a hunt, but if he doesn't leave he stays out of your way. If he can't leave he tries to make sure that he doesn't touch your food.

Sam

Sam usually knows before you do when you are about to start, and he has everything ready. Your favorite ice cream, pads and tampons, you favorite tv show on DVD and a warm blanket. He also forces Dean to leave for a week so he won't make you mad.

Cas

He has no idea why you get so pissy. He is so confused why you snap at everyone and he has to have Dean or Sam explain it to him why you are so mad. After he figures out why you are acting like this, he has Sam help him get some of your favorite things.

Chuck

He is God... so he normally just hides in heaven until the weeks over and he doesn't have to worry about you threatening to cut his privates off, cause even God fears a woman on her period.

Lucifer

He likes taking a trip to Hell for a week... and sometimes longer. He hates to be home when it is that time because... you are Mother Nature yourself... and it's one hundred percent worse for you then others.

Michael

He spends the week laying in bed with you. He has angels get everything you need and he has a heating pad with your name on it.

Gabriel

Sweets, he gets all the sweets that you love. He also will cuddle with you and just spend the week relaxing.

Crowley

He takes off that whole week and spends it doing whatever you want. He tries to keep you happy so he doesn't have to fear your wrath.
