Every month, a couple of days before my period i get a sore throat, runny nose/sneezing & coughing. i feel really sick. what could this be from?

High odds previous: emotional experiences, understandings, events associated with being a women, having periods, sexual issues, etc., from earlier times in life. Primary controls of our behavior(s) are always determined by past history/experiences, beliefs & Déjà vu anticipation/preparation for these, or similar events, happening again. Ask yourself what would make sense of such feelings & you will be close.
