You are typically experiencing side effects of Mirena, I will list some below -
Mirena IUD is a foreign object that is introduced into the body and brown discharge or bleeding are common for the first few weeks after insertion. Wear a panty liner or a light maxi pad – use unscented panty liners or pads
- If the brown discharge has a strong odor, it could be a sign of an infection other than Pelvic Inflammatory Disease. Visit your doctor immediately
- Take care of vaginal hygiene – keep the area clean. Regular baths or showers will help you feel fresh and clean. Do not use harsh soaps on the genital area. Use a fragrance-free soap or body wash
- If you are fed up of brown discharge, never attempt to remove the IUD by yourself. Better visit your doctor for advice.
Please visit a doctor ASAP. Good luck
