I feel like I'm constantly bleeding

Hi guys, I had the copper iud inserted 5 months ago and it's been the worst experience of my life! The first month after it being inserted I spotted for 2 weeks then had a 3 week period. It repeated again shortly after It stopped!( I swear like a week)things have died down a bit, Now I have a two week break from my period then bam again! My period lasts 2 weeks its ridiculous, and it's extremely frustrating and it's ruining my relationship with significant other, will it ever stop? Has anyone experienced anything like this?
