I am so sorry you suffered for so long before doing your own research and finding the answer. Thank goodness you didn’t give up and just accept your doctors’ dismissal.
I have a Paraguard IUD (no hormones) that seems to be perfectly fine for me. I explicitly told my doctor I’d don’t want any hormones as being on the pill was not a positive experience. Perhaps that might be worth looking into for you? Best wishes as you recover from this ordeal!
