My period symptoms are weird

I get no pms symptoms and if I do they aren't very noticeable.

Though, hours before AF comes I get very thirsty and when I'm that thirsty I get very cranky. Don't ask me why, but when I don't have water I get very snappy. It's almost like a craving, which is really weird. I drink probably 50oz of water every day, but for some reason during this time of month I get very thirsty.

I get really hot too. Like if I step outside of my cool room for even 2 minutes I start getting clammy. Then when I go back to my room I have to take off my shirt and just sit there for a bit to cool down. I have other symptoms too of course, but those are my only weird ones
