Hi, for the last 4 months my period flow is very unusual, its very little and dark in color. i left the birth control (yazz) a few weeks ago- had my period and started ovulating 2 days ago. i have a lot of pain in my bladder area.

Abn period w/ BC: Change in period occurs w/BC use and it may take a while to normalize after cessation. The pain in the bladder area should be evaluated- may be UTI ( urine) or tubal infection if sexually active. Uterine ultrasound could check for issues, if concern.
