i understand what your going through not sure the cause because i have not yet visited a doctor i'm seventeen and just got married but also have not had a period since may 2013 and it's now november 2013. this may not help but you know your not alone. and i'm not pregnant.!
missed periods months at a time. so for the past two summers i have missed my periods. in 2012 i had three periods before july nothing in june through december. my doctor gave me medication to make me have a period which i didn't take because i had a period before i started taking them. in 2013 i had four periods but then missed july through now- november 2013. i had my first period at 14 and now i am 17. i also have type 1 diabetes and have had always had irregular periods but now i have lower stomach discomfort.
