I think you should probably trust numbers from an independent website.

Those statistics are from the FDA's site, which one would think would be
pretty independent!

LOL Fair enough! I *do* wonder how they gather their info, though.

Yeah, I'm not sure, either. After looking at that one, I checked Planned
Parenthood's site and they quoted a 0.1% failure rate for the Mirena in both
actual and "perfect" use. So I don't know where the numbers on the FDA's
site came from.
