Well , I started the Nuvaring as soon as my period came on last Wednesday , as I was told by my doctor to do so . And it made my period light , but made me cramp for 4 days straight . So I took it out on the fourth day because I thought the cramps would stop . On the 5th day , my period went off as it should ; but came back on later that night . It was weird because it was brown at first . But the next day it was bright red and heavy and has been that way since . It is the fourth day since it came back on and still cramping , still heavy and seems like clots coming out . What's wrong with me ? Could it be a miscarriage ? I'm scared because I might be losing too much blood ! :/ (This is very abnormal for my period !)
