Thanks for writing in .
After placing Mirena
, your periods will become irregular, unpredictable.
Spotting may increase. Periods over time may become shorter.
Your periods may stop altogether for as long as you have Mirena (they will return once it is removed by your healthcare provider).
So do not worry. But if periods remain heavy and frequent even after 6 months; then you need to take call and ask your doctor for removal if required.
Wish you good health.
