If you have two people in the barracks and they are in the process to get pregnant, (they actually go into the back room)if you have any kind of emergency, IE. Fire, rad roach and so on, after the emergencies finished, the people come out and go through the same process again, as, she's not pregnant. It tells you there having a baby, it gives you rewards as if she was having a baby (if there was a reward for getting someone pregnant) the only thing you don't get is the actual pregnancy. Becoming a pain as I've just had it happen four times on the trot with the same couple and she still isn't pregnant. On the plus side it completed a reward for getting 6 people pregnant when in reality I've only got two pregnant women. But when you actually want a child to be born becomes annoying as hell.
