Discharge for couple months, HELLP!!

Alright since mid November I've been having this brown 'light period', I wear pads for them so it doesn't leak onto my underwear, but it hasn't stopped and it's now 23rd of January. 

Before getting onto this discharge, I experienced little normal discharge, I was sexually active but stopped at the end of August due to break up. I also was on 'the pill' and an injection which was birth control but only for a month or two months and stopped. The injection lasted for a month and a half so has worn off. 

I had my last period at the end of September I believe, since then I have experienced small bits of period like blood in my pads but nothing like a period.

I mostly certain I'm not pregnant, as I would be almost 6 months pregnant and I have literally had no signs of pregnancy apart from discharge and a small bit of weight gain. 

I do eat pretty unhealthy, and I am a vegetarian since end of November for extra detail.

I am 15 if that helps... thank you 

If it's brown and you came off the injection it'll be all the old blood from the periods that didn't come :-) I'm 15 too x

Thats was I was wondering but surely for only missing 2 periods I wouldn't be having 2-3 months of everyday light discharge?!??! 

is it always brown?? 

sometimes it's blood but most times it is brown 

Your period could just be thrown off by you stopping your birth control suddenly. It could come back to normal in 2-3 months maybe longer everyone's different. I just stopped taking the pill around 2-3 months ago, and I just got horrible pains one day went to hospital and they found an ovarian cyst that was bleeding and my ovaries were also enlarged due to the cyst. And a week after the visit I got my period! Or at least i think it is. could be bleeding from the cyst but I have period cramps so I'm assuming it's regular menstruation. I got to the doctor today to find out some more. Cause I also had a bout with stomach flu and I'm still not feeling well. but you will be fine hon.
