My boyfriend has migraine few days prior to my period every mth.Is there any explanation to this?thx

Before your period your attitude/emotional state can change due to hormone changes, probably without you even knowing it. If you have been together for a long time your emotional state can effect his. He could be sympathetic if you get really crampy before you get your period. I think these reason are good ones :) It means you guys are close and on the right path! My hubby knows when I'm going to get my period before I do lol
