"I was 17 when I got this put in, the insertion process was completely fine;the anaesthetic felt a bit like a really odd dull sting going up and down my arm, but not noticeably painful at all. Felt my skin tugging when the implant went in but again it didn't hurt.  After I got it, I had a couple of months of really odd periods-- it started with random day (or even couple-of-hour) long spotting or really light flow in no sort of cycle, then became very heavy long-lasting periods every fortnight or so. However, they changed again and now I haven't had a period in a good few months, and this has been the longest stage of all of them. It hasn't quite been a year yet but it seems to have settled down like this. I have no regrets about getting it!"
