Ok..this is actually a bit concerning.
no periods for 8 years and no birth control pills means you have been exposed to unopposed estrogen for nearly 8 years...this increases your risk for uterine cancer...and this bleeding could be from uterine hyperplasia or even uterine cancer.
Pregnancy is possible, but unlikely..and, you need to find a way to see someone about this. You need an ultrasound and biopsy of the uterine lining.
Try planned parenthood or see if there is a gynecologist in your area that can help you...apply for federal or state aid..but please follow up on this.
