When will i start my first spell?

when will i get my first extent? i have this discharge for a really long time in a minute. like almost 2 yrs i muse. and often find a really heavy discharge and afterwards it stops. the discharge usually is all the time but sometimes it stops (but not for long). i am REALLY moody, my boobs r really sore, and my put money on hurts, and i am gettting bad cramps. this have also been going on for a while now. i hear somewhere when u r underweight that ur body stops ur extent or makes it not come. i am almost 13 im 5'4 and i weigh 79lbs. could that be y? i am lately so confused right now..

You have adjectives the symtoms, but you have to be 100 lbs & over to receive your period. Dont be afraid
