I was planned in a vague sense. My mother started out intent on having six kids. No, not Mormon or Catholic. She came from a Jewish family that would have been five kids if the one before her hadn't died within days of birth. It was more of a post-WWII thing, where cranking big families was in vogue.
Things didn't go as planned. After my eldest sister there were no more pregnancies for six years. They were looking at adoption when my other sister came along, then my two brothers and me, each with less gap than the previous.
I was born approximately nine months after the JFK assassination. (At the old Cedars of Lebanon Hospital in Los Angeles, which today is the world HQ of Scientology. The TM people are almost next door. I've wondered if they commute together, like the Sheepdog and the Wolf in the old Warner cartoons.) I've kidded my mother a good deal about my parent's 'passionate' reaction to the event.
