Facebook's Mark Zuckerberg and his wife Priscilla Chan are expecting a baby girl! The happy news comes after some tough times. According to a post the CEO shared on Facebook, he and Chan had been trying to conceive for a few years. After suffering three miscarriages, the couple is finally far enough along in this pregnancy to open up about what they went through. "It's a lonely experience," Zuckerberg wrote. "Most people don't discuss miscarriages because you worry your problems will distance you or reflect upon you—as if you're defective or did something to cause this. So you struggle on your own." He hopes by sharing his experience, other people will feel comfortable sharing their own stories. Many congrats to the couple!
