Even sex on the pill is unprotected in the sense of STD transmission because the pill offers you no STD protection.
But I believe what Miz S was referring to the fact that the user had missed a pill. If you don't take your pills correctly (ie. missing pills, taking medications that interact, illness, etc.), then any contact you have should be considered unprotected because of the way the pill works (if not taken correctly, it can fail).
