Hi, I currently have an marinea coil fitted and have done for 8 months, I had this put in due to extreamly heavy and painfull periods. My symptoms have become worse over the last few months, constant heavy bleeding, passing blood clots, in extreame pain in pelvic area, hips and back. Now both iron and b12 deficent. G.P prescribed northesterone last week due to extreamly heavy bleeding for 3 wks prior to take for 2 wks TDS. I have been taking for a week fine, but today feel extreamly tired, headachey, had really bad pain in left groin,hip and lower left back. Just wondering if this is normal? Or to stop taking them and if I do stop taking them will I start to bleed again. Thanks in advance
