Three weeks ago i got the mirena coil on the last day of my period. The cramps for the next week were terrible so i went back to the doctor who checked the strings and said it was fine, gave me painkillers and sent me on my way. The cramps stopped 2 days later. 10 days ago i started bleeding heavily, 2.5 weeks before my period was due. This bleeding is quite heavy and is showing no sign of stopping. I got the mirena to ease my heavy periods. I think I regret my decision getting the mirena coil. I still have slight cramps, no energy or motivation. What will I do?
