Was this a sign?! And if so from who?

I'm pregnant with my second child. When I first found out I went into this strange depression/anxiety over the thought of a miscarriage. I couldn't eat or sleep, my husband was worried.

One night I was crying on the couch and I don't know where this idea came from but I dug up an old Bible from the basement. I closed my eyes, flipped open the page and the first thing I read was "fear not, by this time next year you will be holding your son".

I've never really believed in anything but I instantly felt better, all my worries disappered. I'm not religious so I'm a little confused, who sent me this sign?
