the love you have for your baby.

So I'm a FTM and of course I love my fiancé with everything I have and everything that I am. I love him more then I could ever put into words. This is going to sound weird but the moment you first see your baby is that a moment that you can't describe? Or a love that you can't describe? I probably sound odd haha but I just want to know what it feels like. I'm still getting use to the whole pregnant thing. I guess I'm scared to love someone who isn't my fiancé and then I'm scared I won't love him as much and I feel selfish.
