Lotts Of symptoms not sure whats wronge.Help?

Okey dokey so it started at the begining of this month. I only get my period every other month its been that way for years. So anyway It started early this month. Around the 6th of this month I woke up one morning and for some unusual reason I had to pee every 45 minutes to an hour and wasnt drinkin that much of anything. Next I woke up one morning at around ten and was really sick and throwing up every around 10 minutes until 1 oh clock. Then I became very moody and emotional. Like somthing dumb would make me mad then 2 seconds later I would start crying then I would be all happy. Then Oddly enough I started my period like almost a week early. It lasted 5 days with my usual not to bad cramps. Then about a week later out of the blue one night I felt really hot and my head was warm as if I was running a fever It felt like it was 90 somthing degrees in the house and it was only 79. Yet for some odd reason I was getting chills. Then thirty minutes later I felt fine and It was no longer hot. Then I started getting a small amount of pain in my lower stomach and it isnt cuz I am not drinking water cuz I am. Now My stomache is hard and looks bigger yet Ive gained no weight and its been two weeks since my period. I dont know what it could be but Its not anything I ate cuz I checked as soon as I woke up and this morning I have also peed 3 times in 2 hours.
