I have had an IUD for some time now. About 6 months I would say. My first one did not take so I had to get it removed after only 2 months. The one I have now seems like it has taken. I have the Paraguard,nonhormonal, IUD. They're aren't many studies on it, but I am curious how many ladies here have an IUD and use a menstrual cup. Have you had any problems? I have not, I make sure I break the auction of my diva cup before removing it every time. Let me know your experience, I am curious. ☺
