What will you be doing roughly 13-17 months from now? Maybe you'll finally be taking a stay-cation in sunny Tulum, where you could live by then. Perhaps you'll be starting a new job at the soda can factory. You might even be well into your second pregnancy if you start on the first one right now. Change is scary, but take comfort in the knowledge that while your life may look different 400-500 days from now, one thing is for certain: you'll be able to read former Laguna Beach star Kristin Cavallari's first book then, probably.
