Heavy period

Kaila
I just got the IUD about a month ago... And Ive had my period ever since and really heavy for a month with horrible pain,it got to the point where I had to go to my doctor and he gave me a tablet I have to take 3 times a day at the same times and that will just stop my period cause i started losing iron and had to go on iron tablets that weren't doing anything... Has anyone else had this problem.
