Every time I go to the nurse for my pill check she always tries to talk me into switching to the injection instead. I have to admit that I'm not really convinced that it is the best thing since sliced bread that she is insisting it is but have been considering it recently. I thought it might be good not to have to remember to take a pill every day (I have tried the implant and hated it and I can't have a coil) so at my last appointment when she brought it up I asked for more details.
I did kind of like the sound of it until she mentioned that it's given in your bum (or as she politely called it "your bottom" 
). I had assumed that it would be in your arm like a vaccine.
At this point I kind of went red and said I'll just stick to my pill thanks and left.
I am happy with the pill I'm on, so it's not a great loss...
