Birth Control
"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 :)"
