Just so you know I kind of think that they wouldn't have the same menstrual cycle that we do. I don't know what they would have, but I just think it would be different.
Tries their very best to understand what's happening, but that doesn't work out very well. They will get you pads/tampons but they will be the wrong size or the wrong brand. So don't be surprised if you ask for pads and they bring back liners instead (poor thing will think they actually got you the right thing). If they find out it wasn't what you wanted they will feel horrible. Offers to get you food instead.

Asks for very specific details, might even take a picture of what you have left to make sure they get the right thing. Cuddles. Acts like they don't care about what you're going through

Goes to the store for everything you need and doesn't mess anything up. they are incredibly embarrassed while they get it though. They'll cook for you and give you as many cuddles and massages though.

What's there to be embarrassed about? It's normal for you right? okay then. They'll wash the bloody sheets and (try) cook for you.
