Hi My Name Is Angelica, I Had Been Experiencing Abnormal

Hi my name is angelica, I had been experiencing abnormal periods since I had my second son a year and a half ago. I was getting it every 2 months, till 4 months ago I got a period and didn't see one till 3 months later. on December 1 started spotting wich that's a sign of period with cramps and muscle pain. anyhow its jan 8 and im still on my period. im passing clots everyday but they arent as big as a golf ball. now my question is what could this mean is it something i should really worry about. i just don't have insurance and its too pricey to just do a doctor visit for nothing. please help me... my email is YYYY@YYYY
