Hello, and I hope I can help you today.
Most women have irregular bleeding in the first month or so after getting a Mirena
. The reason that happens is that the Mirena does not affect your ovulation or hormone levels. In the first cycle after the insertion, your uterine lining has to adjust to the effects of the progesterone
in the IUD, so you may have a long, irregular period. After the bleeding slows down or stops, most women either do not menstruate at all or have short, light periods.
However, some women can have irregular bleeding and spotting for even 6 months with Mirena. These are all side effects that are not dangerous, but will improve with time.
I hope I was able to adequately answer your question today and that this information was helpful.
Best wishes, Dr. Brown
