Hi everyone please help I just had my period on march 1 through like the 5th and now on march 13, I have it again. I don't know what it could possibly be my boyfriend says its possible I'm pregnant but doesn't it means if you are on your period you are not pregnant. RIGHT? Im not on any type of birth control so it can't be that and I don't take any medications. Does anyone possibly know what's wrong with me?? Help please and thanks to all.
