pregnancy - WTF?

Why is everyone pregnant? My hairdresser is 7 weeks pregnant with her 4th child. Her husband and she are doing the "natural family planning" recommended by the Catholic Church. You basically track when you're ovulating and don't have sexual relations during that time to avoid pregnancy. The church is so against birth control so they recommend NFP. I'm pretty sure she and her husband didn't plan this fourth child but it's just proof that whatever the church is recommending - IS BROKEN! In addition to that - is the church going to be paying for this 4th mouth? Doubt it.
