i just turned 21 a few months ago.when i was 18 i went to the doctor and found out that i had hpv...it was never treated it just went away on its own.up until about 5 months ago my period has been completely normal now it is anything but.my peroids prior would last about 4 days with no pain at all.now my periods are rediculous.....i'll bleed for a day or two with no warning at all and then it'll stop all through out the month.or i'll bleed for a long time and bleed so much that i need to change my tampon every hour or less and it's very painful.there is only a few days out of the month when there is no sign of blood at all.in the last fews months i have also had horrible back pains. i was searching online for answers and i checked my cervix for bumps and there is something on the cervix not sure what though.its also painful to have sex.basically i havent made an appointment for a doctor yet because i'm scared of what they'll tell me.any answers please.....
