Implanon
"I'm reaching the end of my first Implanon stint. I've had it for nearly three years now and it's been interesting. Before I was on the pill and never had any side effects so I thought I wouldn't have any with this one. 

Getting it put in hurt like hell. Some people didn't bruise apparently, my arm looked like it had been broken. It was black and blue and sore for about two weeks. After that my periods became less and less frequent. I've always been irregular so that was fine and for the second year that I had the implant I barely had a period. Maybe one or two days every few months. 

Now on the third year I'm find that the bleeding is very minimal but almost constant. Every time I have sex my period will start up and last for about a week."
