To be fair, this is true for any working form of birth control, but if the pill wants to be women's savior with the I-changed-women's-lives angle, then it will inevitably be our foe.

The technology has improved drastically in the last five years and its cost is becoming less prohibitive, so it's expected to be a viable option soon. If money weren't an issue, would you freeze yours?
