I had a mirena (levonorgestrel) coil fitted in nov 2011 and bled the whole time until I had it out in may 2012 and I haven't stopped bleeding also my discharge is thick?

Not normal. You need to see your gyn for an exam, cultures to r/o infection, blood work and an ultrasound, that is what i would do and then i woul know how to treat u, so make an appt , yoiur problems have been going on way too long.
