Just a quick note on the stats...
When they say the pill is 99%+ effective, they mean that of 100 women having sex for a year (average 100 times) there would be 1 pregnancy (for 99%); 0.5 pregnancies (for 99.5%) etc...

So 99% means you'd get 1 pregnancy for every 10,000 times you have sex; and a lot of pills (used correctly) claim better results than that!
