"I am in a big dilemma. I am taking the contraceptive pill, but I have rather unpleasant side effects."

The main differences between a hormonal IUD and a copper IUD are the presence of hormones and the potential side effects. Hormonal IUDs may have a lower risk of blood clots but can still cause side effects such as weight gain. It is important to consider all options and discuss with a healthcare provider to find the best method for you.
