One minute, you’re giddily shopping for tiny onesies and planning your babymoon; the next, you’re weeping uncontrollably over the fact that life as you know it is about to change forever. Mood swings during pregnancy are extremely common, says Alex Robles, M.D., a board-certified ob-gyn at Columbia University Irving Medical Center, in New York City.
