Is it normal to have your period twice in one month
I am 17 and i am in a stable relationship with my boyfriend of 4 years. During the month of December in 2012 i had my period twice and i have not had it again yet and i was wondering if this had happened to anyone else before and if this is a normal thing. I have not experienced anything like this before and neither have my family. I come from a big family and this has not happened to any other family members. Any answers would be appreciated.
