"i had the mirena iud placed 4 weeks ago. i had heard that the initial placement can be very painful, however, i only felt a very slight ache/pressure when my doc put it in. he even had to manually expand my cervix because it wouldn&#039;t open for him at all. but even with that, it wasn&#039;t bad. i did bleed quite a bit after insertion because he had to pry everything open basically lol. but really not a bad experience. i rated it at an 8 because i&#039;ve been bleeding since about day 5 post insertion. it varies from light spotting to full blown period heaviness from day to day (cramps too) and hasn&#039;t stopped for 3 weeks. its quite a mood killer :/ but i&#039;d still choose this over the pill, honestly. the bleeding is the only downside for me."
