Cervical erosion and IUD strings

I've developed cervical erosion since having a baby.

I got Copper IUD since baby. I've noticed that when the string is down outside of the cervix I constantly spot. But when it moves up into the cervix.( I can still feel it right thsre but it doesn't stick out enough to touch my cervix) If that makes since. I don't bleed at all.

Would cutting the strings be a solution to stopping the spotting?? I feel like it would but my husband seems to think I should wait it out cuz everything says it can take 3-6 months for it to soften and your body to get used to it. Easy for him to say it's not his body.
