I hear ya. I'd be happy, but caught off guard right now, too. I kind of joked with my husband about the next pregnancy might have to be unplanned for me to actually go through another one, lol. Meaning, I may never get my nerves up to do it, otherwise!
Have you seen the shows about women not knowing that they were pregnant, then going into labor & having a baby all of a sudden? This sounds pretty great (aside not having the needed medical care that we PE ladies would need...which is a huge deal breaker, lol).
Whatever the cause, I hope that the outcome is wonderful for you! I know that you'll keep us posted. :0)
