Hi, I had the contraceptive impant put in my arm back in December 2004, it lasts 3 years and is due out this december
You cant really see it,you can feel it if you look for it but for me I have had nothing but good side effects ( no PMT, no periods and no weight gain)
Would receommend you speak to your doctor about it, some doctors seem quite happy dishing out the pilltime and time again.
For me, i am not looking at starting a family for some time, so you can just forget about it
Should you then want to try for a baby you can have it removd at any time
Hope this helps!
