Levonorgestrel
"Was on microgynon for two years because of heavy periods, and while it worked I was awful at remembering to take it.

So I heard mirena could be an alternative and after a bit of research reading both really positive and really negative reviews I figured it was different for everyone and I wouldn't know unless I tried it myself. 

I was a little scared as not only have I never had a child, I am a Virgin ( age 20). 

But I took two paracetamol and went in completed relaxed listening to music. if you stress you will tighten up and it will inevitably hurt more. 

Yes it hurt,but for about 5 mins. I bled the first day, but not since. It's been three months, no spotting or bleeding at all. Incredible, best decision I made. Pain killers+relax=success"
