When a girl tell you she having period what is she trying to say?

Depends on your relation with her it can range from:
"No sex today ", to a different more specific way of saying "I am not feeling well, if you can be a place of distraction that would be apreciated".

Also it can be a way of you showing her you are not only about sex. If that was your goal and after she told you that you ignore her for the day, than this gives a huge fuckboy vibe. So be careful not saying something can mean more than you think.

expect her to be of shorter temper and in pain. if she's a close friend/intimate person with you, she probably could do with some sort of support/comfort from you.

Depending on your relationship with her and the tone.
Leave me alone.
No sex.
Warning, I might be grumpy, don't take it personal.
Please comfort me.
Please give me snacks, drinks, a nice warm blanked and entertainment to make this easier.
