What does it mean when you bleed but have an IUD?

Bleeding with an IUD can occur for various reasons, including hormonal changes, the device's presence irritating the uterine lining, or a potential infection. Some individuals may experience lighter or irregular periods, while others may have breakthrough bleeding. However, if the bleeding is heavy, prolonged, or accompanied by severe pain, it's important to consult a healthcare provider to rule out complications such as displacement or infection.
