Had 2 normal periods after child birth then started bleeding for the last 2 weeks, have had pelvic pain in the bone. starting to hurt worse.?

May have 2 things: Going on, u may post partum uterine atony, or retained products of conception in the uterus , so you will, so you will need an exam and an ultrasound by your ob, and you may have pain from pubic symphysis separation if it is right in the front , an MRI can diagnose this or sometimes an xray so both problems need to be evaluated.
