A few days before my period I start getting into my head really bad about my boyfriend cheating on me, I get really emotional, I cry a lot & not sure how to fix this. I know he’s not cheating, he’s never gave me any reason at all to believe he is. This happens every single time before my period, other than that I’m completely fine & happy with him. Does anyone else suffer with this & if you do what do you do to fix it?
