His and Her Health

Hi, I'm new here. I need help/have a question. I'm 26, reletivley healthy with no known medical problems. most of my adult life I have had pretty mild/normal periods. I've noticed the past couple of years that my cramps have steadily gotten worse. the last year, I've become much more emotional and had breakouts right before starting. these seemed pretty normal, tho irritating.
well, the past few months I have noticed a definite trend of getting sick before starting my period. it starts with fatigue and turns into a low fever with headache and burning eyes, and a good deal of nausea (no vomiting and I can eat food), in addition to aches, very flu like.

I'm going nuts trying to figure out a corelation between this and my period, hoping it is normal and there isn't something wrong with me. I'm fairly certain I don't have endometriosis, gonorea or chlamydia.

anyone have any thoughts?
