I have more then 1 period in a month does that sound serious?
every women is different, and there could be health related reasons. My friend had her period more then not in a months time. But she is in her 40's and went to a doctor to take care of this.
So I would say talk to your mother and talk to your obgyn, I think anytime a women starts her period she should start seeing a obgyn.
like 2 times a month?? it can be caused by stress etc but if its every month... you should see a doctor
like 2 + periods every month?? or does it vary.. it could be an irregular period.
