Ran across this poem by Sharon Olds in my student's anthology--had never seen it before:

The Planned Child

I hated the fact that they had planned me, she had taken
a cardboard out of his shirt from the laundry
as if sliding the backbone up out of his body,
and made a chart of the month and put
her temperature on it, rising and falling,
to know the day to make me--I would have
liked to have been conceived in heat,
in haste, by mistake, in love, in sex,
not on cardboard, the little x on the
rising line that did not fall again.

But when a friend was pouring wine
and said that I seem to have been a child who had been wanted,
I took the wine against my lips
as if my mouth were moving along
that valved wall in my mother's body, she was
bearing down, and then breathing from the mask, and then
bearing down, pressing me out into
the world that was not enough for her without me in it,
not the moon, the sun, Orion
cartwheeling across the dark, not
the earth, the sea--none of it
was enough, for her, without me.

I sort of loved it, except for a mixed reaction along the lines of "Dumbass. You needed your friend to tell you before you realized? Dumbass."
