"i got the mirena fitted on the 13th feb, having it fitted wasn&#039;t to bad, just felt a little uncomfortable. but after, it was fitted i did experience the worse cramps ever, it was so painful - i&#039;ve never had children so i don&#039;t know if it was because of that. 
i bled consecutively for 4 weeks, heavy bleeding for 1 then really light, spotting for 3. however i didn&#039;t have a single cramp.

soon after that, i&#039;ve had no bleeding, no pains. no periods since so it seems to be doing the job, i think you&#039;ve just got to persevere with it and let it get use to your body before you start criticising it. however it doesn&#039;t work for everyone :)"
