hi,my period does not come every month,and even if it does at times i bleed for a very long time(2WEEKS OR MORE)i have been going to d hospital for close to three years now and i was told i have a mass in my ovary..when i went for another check up,i was told it was no longer there.though i used a pill which regulated it for a while.now its five days.I did not see my period from september last year till last month which was on the first,it was supposed to be on d  first of February but i have not seen it..do i need to be worried about it ,does it lead to Fibroid,would it affect me in giving birth?(though i have not had sex before)
