I am a bit worried, I haven't started my period yet and it has almost been a month. I am tired all the time, drinking a lot, and have to use the restroom all the time. Smells are getting to me,I am tired all the time. No matter how much sleep I get, I am tired all the time. My back hurts and my head hurts, I feel sick to my stomach all the time, I am dizzy a lot. I have the emotional stability of a two year old...and I am starting to get a bit worried...I don't know why....I had a period last month, but it was very very light...and only lasted two days.....any advice?
