[|Human|] i have had mirena coil for nealy 3 years and i used to get spots of blood but this month i have had really dark blood and lots of it. what could this be? i am 27, weigh 10stone and am 5f 6. i have been havin pain in my lower stomoch but been tested for pelvic inflamitory and cysts which were all clear
[|AI|]  Howell come to Chat Doctor If this is dark color of bleeding P/v then this is nothing to worry because such dark color sometime noted in delayed menses some time this could be due to collection of menses inside uterine cavity for hours, then expelled out, in short this is just nothing to worry, if you have a history of IUD then this need to be seen for proper position and for this get done the ultrasonography test, hope this information helps, take care have a nice day.
