I had my menstruation last June 28, 2013 for 3 days and I was confusing why I got my period again this nine of July and until now I am bleeding but not heavy, is there any posibilities that I got miscarriage?

Only a Dr can tell. My sister took a pregnancy tesa few says after she got pregnant. Went to the Drs within the month and found out she had lost it. There is no other way to tell than the Dr..
