So I'm 19 just had my son a year ago.... Tryed differnt types of birth controls and then stopped taking them... Now when I put a tampon in it is light bleeding when I take it out in a couple of hours but when I dont put one in no blood comes out. I did have a cyst in my overies but I took medication and it went away so If I what it could be this has been going on for about half a year now
