Why is my Mirena IUS causing strong ongoing cramps a week post-insertion?

Strong ongoing cramps a week after Mirena IUS insertion can be due to several factors, including the body's adjustment to the device, inflammation at the insertion site, or hormonal changes. It's common to experience cramping as the uterus reacts to the presence of the IUS. However, if the pain is severe or persistent, it's important to consult your healthcare provider to rule out complications such as infection or improper placement. They can provide guidance on managing symptoms and ensure your IUS is functioning correctly.
