tubals are known to come undone.. they are not 100% foolproof.
The U.S. Collaborative Review of Sterilization (CREST) found the failure rate for tubal ligation (all occlusion methods) to be 1.85% after 10 years.
for some reason, they say that if you get your tubes tied during a C-section they tend to fail at a slightly higher rate.
uh... disregard my second comment. thats not even my comment lol. i tried to copy and paste another link (i think) and I'm not exactly sure what i copied and pasted. It was "supposed to be" an Ivillage report and not quite sure what ended up happening.
umm.. wow. are the forums messing up?
as soon as i posted my last, the weird comment about white tongues disappeared.
i think i better go lie down lol
