I'm 21 years old, never been on the pill.. Ive not started my period since Nov. In Dec. I thought I had started but it only lasted for a few hours and I spotted little 2days after that. I took a test to see if I was but it said no. Its almost Feb. and I still ain't started. Ive gained some weight, my belly has got a little bigger but not too much, like you can tell when I got a shirt on. I eat and eat and don't get full, I always have to have something to drank, my lower back is about to kill, I ain't tired but yet I want to lay in bed all day and sleep, I feel weak, sometimes I feel so alone... I don't know what is going on inside of me. If you can please help me, I need to know cause if I'am and don't know and I end up loseind it cause I didn't no it will bring me so far down in life! Thank you for takeing the time to read and answer this.

Ermmm... have you ever considered going for a visit at your gynaecologist?
And have you had sex in nov?
