What's with the blog name?

The title of this blog came from my friend, Stephanie. I'd called her about medication (she's not "almost a nurse" anymore... she IS a nurse!) and when I told her she said "You're like the One Hit Wonder! All of my pregnancies I've been so so so incredibly lucky to get pregnant the first month. I don't take this for granted and I am extremely thankful every time. I can't believe it, again, the 4th time... first try. Craziness.
