hormonal paranoia?

I get paranoid like a week before my period. I assume everybody is lying to me and doing things behind my back. my boyfriend especially. if he doesn't call me like he usually does, I think he's up to something. if he stays at work later than usual, I think he's with someone else. then, the feeling just disappears. which leads me to believe it's either hormonal or he stopped doing whatever he's doing. my intuition has never been wrong but I really can't tell if it's because of my period or if im being unnecessarily paranoid. my boyfriend has never done anything to make me not trust him and he's a good man. has any of you had this problem?
