Hi, I was put on yaz because i have severe endometriosis, I am 24 and was advised against having the mirena coil as I haven't had any children yet, I was willing to give it a go because of the severe symptoms that I get with my endometriosis, however since i started it two months ago, i haven't stopped bleeding, not even for a day, my breasts feel as if they are being twisted, the pain is awful,(however they do seem a little bigger) i suffer from extreme fatigue, the back ache is unbearable, headaches beyond belief and I dont know what to do next? Do I stop the yaz so I dont bleed constantly or suffer from the back and headaches with the risk of my breasts shrinking again?? Or do I stick it out and hope that my symptoms improve the longer I take it. I do not take the 4 white pills as I have been advised by doctor to take it continuously, the idea behind that theory was to stop my periods, however I haven't stopped bleeding since starting the damn thing!! Any advise, ideas????? I have also experienced mood swings with this pill, i cry for any reason now, uncontrollable crying, its crazy!!!
