Imagine the irony: You spend most of your young adult life trying not to get pregnant. Then when you’re ready to be in the pink or blue, month after month that stupid pregnancy test says no. That’s the reality for the 1 in 8 couples who have trouble conceiving. Yep, it’s that many. Don’t think you know anyone? Take it from someone who hid it from most of her friends—they’re just not telling you. Keep these facts in mind should they choose to confide.
