I've been on my period for 4 months straight, with one or two days within that off. I've been to the doctors and had scans it's not polycystic ovaries or an sti. I have been given two tablets to stop my period which have stopped working. I'm 20, and on the mini pill as I get migraines, but this pill has never ever caused issues if anything it stopped my periods. Need help stopping my periods, as I've had to go off sick at work due to being so tired and poorly all the time. Any advice please.
