Had one for 8 years - well, on the second one now, as you have to have them changed after 5 or so years, depending on the brand. Mine's a Nova-T, I think. Absolutely fine, no problems, and totally recommend - I don't fancy the hormone route either.
It's not the most comfortable procedure in the world, but not the worst either (you've given birth, n'est pas?!). Take a couple of ibuprofen before you go and it's fine, really, just a bit uncomfortable and you feel a bit of pushing, maybe a sharp pain or two, but really not that bad - for my first a nurse held my hand (her idea, not mine) and I lay there thinking, for goodness sake, what are you like?!
Once it's in, if you're like me you'll find that you have pretty much constant clear discharge for a few months, and heavier periods - Super Plus every 3 hours or so maybe. For me, it then settled, and whilst I'm a bit heavier than I was before, it's not that heavy really, perfectly manageable.
When my coil was changed 2 years ago, I was a bit heavier for a couple of months then it settled back.
I find it ideal - being a typical married woman sex happens not that often or regularly so you're not taking pills/hormones for nothing for 30 days out of 31 but you're ready to go when the moment arises!
My strings disappeared once, but came back down next period. They're not intrusive, don't cause a problem.
All in all, a postive thing in my opinion.
Right, off to start a thread about my own current issue...
