"The panel also noted that PP accepted the small pregnancy risk that exists when a woman takes the pill and has unprotected sex."

Another way of describing this situation: The Pill is not 100% effective, even if your partner uses it, so always cover up with a condom.

The Pill also does nothing to prevent transmission of STDs, so the combination of both methods is better than either one alone.

I would have expected a doctor to know that, and to demonstrate better sexual hygiene / safer sex.

When you have unprotected sex you are having unprotected sex with everyone your partner previously had unprotected sex with.
