I'm a 21 year old female in good health. I have some odd symptoms that I've never had before. I've been having bad cramps for about a week and a half now. They're like full blown menstrual cramps but my period isn't due until next week. I have pretty bad acid reflux as well as bloating, extreme fatigue, and just recently started having crazy mood swings. I'm very irritable. Any ideas what this could be? It would be nice for someone to reply to one of my posts for once... Thanks Oh and I'm not on any medication
