Period since IUD

lia

I got an iud placed almost 5 months ago, and my period has gotten longer and heavier since and I am MISERABLE! It’s getting so expensive because I am going through so many tampons and Motrin. I talked to my Gyno and she said it’s normal because it takes like 6 months to get used to it but it just doesn’t seem normal to me. Please let me know your thoughts on what I should do or if this is normal.
