Second babies

I'm gonna be 7 weeks.. And this is my second baby. I didn't have any morning sickness or anything with my first and still none yet. I was (still am) hoping for a different pregnancy this time! I want a girl this time around, my last one was a boy. I feel like this is gonna be the same.. No symptoms (i guess I'm really lucky actually). And I'm hoping that tummy comes in soon! Ladies when did u start to show with your second and how did your pregnancies differ, or not? I don't think I showed with my first until 10weeks+
