Is continual spotting after having Mirena inserted normal? Will it
 eventually go away?

Spotting is considered a normal side effect of Mirena. While it tends to decrease over time, everyone’s body is different! Take a peek at the handout you received at the insertion; this should provide more detailed information about what to expect.  With more questions about Mirena, call Teen Clinic to talk to a provider: 303-442-5160.
