Women burn more cals before their period?

I read that women burn anywhere from 200-500 extra calories a day the week before their period, due to an uptick in their metabolic rate. Got this info on some random site last night and was wondering if anyone might have a legit source to back it up...

I've really struggled with eating under my calories this week and wondered if that might be the hunger igniter. I know PMS in general can be.
