I had my period a week ago, but there was barely any blood it lasted about 2 days then the rest of the days it was nothing but brown discharge , my period usually last, 5 days. Another week went by and now the brown discharge is back with cramps , more frequent when im laying down, I do not know what is causing this almst 3 weeks ago I went to the doctor and I had a bacterial infection and I took a perscription for a week to get rid of the infection, I dont know if that is the reason why Im having cramps and brown discharge, im not on birth control , & I dont have insurance and dont have the money for another drs appointment, what could cause this?
