Hi Lottie, Small world, First I would have a good read up
about depo shot side effects, this may throw up
a couple of clues, depo shot does not have a very nice reputation for giving problems, why other women think its a gift from god, till they have to come off it.
Knowing what a coil will do, try forgetting that.
But do you think this could be the start of your menopause?
But I would get back to your doctor and ask for a gyno appointment, you may find better help there.
