June Morgan at Rex Morgan, MD, is pregnant. She's a nurse, and it looks like Rex was totally caught off-guard, as in this was not planned. She knows what causes it, and what can prevent it, and that no matter what (except for sterilization) that there is going to be a 3% failure rate, and we have no clue of why she would have planned one. Anyway, Rex is all giddy happy about it.
Compare to a certain pharmacist, who had to apologize to her husband about messing up her birth control, and having a stranger make a comment about a "planned accident." Of course, said pharmacist's husband was going to take off for a year, and had to quit his plans, but still, Dawn conceived before Mike started announcing his plans.
