I'm having my period longer than unsual and I'm pre-menpasal stage and my periods use to stop and barely show it was pink,and now its heavy and lasting longer for the past two months.It's now hasn't stop for two weeks,and I'm worried because I started my period at,11 yrs. old and I had four children and don't want anymore.Also, my pap smears has been normal since being dianosed with hpv,two yrs. ago.What should I do.I know I need to go to the doctor.
