Hello, and I hope I can help you today.
It is not unusual for the
Mirena IUD to cause
irregular periods, and any woman, once in a while, can skip her menstrual cycle just from chance alone. Many women also completely stop menstruating on the Mirena especially when they have used it for a long time, which is a side effect of the IUD and
menstruation typically resumes if the IUD is removed.
So as long as your
pregnancy test is negative, there is no reason to worry if you do not menstruate while you have the Mirena in place. You should check for the presence of the string to make sure that the IUD is still in place. If for some reason you cannot feel the string, you should see a GYN doctor or health provider who can just make sure that the Mirena still inside and functioning properly.
Just remember that the Mirena is effective for five years, which means that you will need to get a new one in another year if you decide to continue using it as your form of birth control.
I hope that I was adequately able to answer your question today, and that this information was reassuring.
Best wishes,
Dr. Brown
