The whole concept of fertility, of deciding when you need to get pregnant, and then having it actually happen the way you planned, never quite worked for me.
I was single until age 34, and then we weren’t ready for a baby right away. We just timed my cycle, figuring if we got pregnant, fine. But the later the better.
Then, a new gynecologist asked what I was using for contraception. I told her that I’d been using natural family planning — smug that I’d managed to make it work for more than a year.
“So, nothing,” she said.
