I haven't had my period for 2 months. Never had sex so i cannot be pregnant. I dont know what could be wrong? It was suppost to come somewhere on the 23 or early 20s but I still didn't get it. In the begining of June thought I did a 6 day water fast to lose weight and I lost about 12 lbs and then gained it back plus more the following week , and I was suppost to get my period in the early 20s of June but I did not. so maybe it could be because of that. I've never had sex in my life nor have I ever been with a guy in any sexual way. not lying. Sometimes I have weird feelings in my stomach and feel bloated and my stomach feels muscular and hurts if i press it with my hand and that started happening like 3 or 4 weeks ago. I had some light spotting and brown discharge for only like barely 2 days about 2 weeks ago and thats it  Also these days i have some small cramps in my abdomen. It's been going on for a couple of weeks now. I am 17. Been having my period for like 2 years and I've only missed it once before but only for one month. Now its 3 months and I haven't had it yet. I have a random exercise days where somedays I will run for an hour and some not. Also, I eat randomly too like I'll eat a bit one day, another nothing at all and somedays alot. I am trying to lose weight but that 6 day fast made me gain 7 pounds. I will be going to the doctor on thursday to get a stomach scan or smtng like that. Could there be anything serious wrong?
