"i am 20 years old and never had a child or been pregnant, and i decided to go with mirena after much thought. i was pretty nervous going into it, and i&#039;m not going to lie, insertion was pretty painful. i would recommend taking that day off for anyone, but by the next day i felt better, and by the second day i was back to the gym. the first month was pretty much continuous bleeding, but i have now had mirena for 4 months and i must say the pain of insertion and bleeding was worth it! i would definitely recommend sticking it out, considering that you can keep it for 5 years!"
