What could stop my period completely?????
since you have ruled out the most obvious, i just have to ask, have you had a d&c or any procedure to your cervix and/or uterus recently? sometimes if you are scarred your period will stop (asherman's syndrome). you can get a saline sonogram or hsg to check for this if you have in fact had a surgery before/around september. or, your hormones may be off or something. i'd go to your doc, they could simply run some tests. good luck.
