What Is The Bleeding And Pain After Fitted With Mirena?

I had the mirena fitted in sept 09 whilst under anaesthetic for endometriosis treatment, then taken out in may 10! had more pain recently due to endometriosis coming back and then had another mirena fitted in early feb of this year. I have bled ever since and have had some horrible pains, not sure if endo pain or mirena pain...too affraid to go to gp due to possible time wasting. I am seeing my gynae consultant in may should i wait or do you think it is worth checking?
