It's handy for sure, but to add a new tangent to this thread, it's only as good as long as the pills are manufactured correctly. And in late 2011, and early 2012 alone, I've heard of 2 recall flaws in birth control pills.
Don't scare people dude. Pills are really effective. Of you want to be extra sure though you can always double up and use a condom as well.
First, the op- never did. The packet itself is labelled by day. Secondly, a recall notice isn't scaring people. The pill fails with regularity, two women per 1000 users, extracted in a year format. Meaning in one year, two out of 1000 users will have pill failure. Many will be "extra heavy periods" and not detected as pregnancies.
