Its different for everyone with every pregnancy. And it can take as long as 24 weeks before you feel your baby.
This is my first too an I started showing very early ever person is different when carring a child and I felt my little girl at like 16 week it feels like gas at first but the more you grow you will feel the punches and kicks and morning sickness is no fun so be glad you don't have it
You dont show much with your first baby. But towards the end you will get super big. And morning sickness not everyone gets it. Be happy if you dont get it, i lost so much weight because of it. And again you wont feel your baby move until the next couple weeks or so. Since its your first you wont feel it, but pretty sure the baby is moving like crazy in there.
