If a MAN can have a baby, why can't I?

Ok, NOW I'm bitter. First of all, my day has sucked so I'm already in a pissy mood. Then I watch Oprah and "Thomas" is on there because he is pregnant. Yeah, that rubbed me the wrong way. If God would let Thomas and his wife have a baby, why won't he let me have one? I beginning to see why they say life is not fair.
