I am a 20 year old female, Im about 5 6 and weight roughly 123. I have had a sore throat for a few days, but in the last 2 days, its become body aches and occasional fever. I also had a bowel movement about an hour ago that was green and runny almost like water. I also am on my period for the second time this month, and it is much heavier than last and will be 8 days tomorrow. What could be wrong with me?
