Ok so I am 18 and have had my period since I was 10. I was suppose to get my period 11 days ago and I've been having lower back cramps, side cramps, and ovarian cramps. I have to keep peeing and it feels like my kidneys that are hurting. Well today i am getting brown spotting here and there. I am not sexually active all i have done is masturbated and because i was so paranoid that i somehow magically got pregnant I took a pregnancy test this morning and it was negative. A few hours after I did the test that's when I started having light brown spotting. I do have ovarian cyst and thought maybe one ruptured. I have also though maybe I have a kidney infection. But I'm still not sure. Please help? God Bless!
