I have no idea what the side-effects will be. I had an IUD put in once. It had a low-dose hormone. I bled for 45 days straight after insertion. They had to give me something to make it stop. After that I loved the IUD. Greatest BC invention ever. Now I've got fool-proof BC: no uterus. Had fibroids that also made me bleed non-stop so I got a hysterectomy. Now I've learned from the iodine thread that fibroids and iodine deficiency go together.
Sorry for the totally useless tangent.
