Two days before my period, I started having really bad symptoms. I have a cut on the corner of my mouth that got infected, my tonsils are swollen, my tongue is sore, and for two days in a row I've experienced fever-like symptoms, as in extreme cold, body pains, extreme weakness. They disappeared after I took a generic medicine for period pains, but my mouth and throat are still in terrible conditions. Usually the flow is pretty heavy and bright red, but so far this time it's being dark pink at best, and not heavy at all. Should I seek help immediately?
