Is it normal?

I received the amazing news that I am pregnant with our first child. This was planned and our first month trying. I didn't think it would happen SO quickly and am so overjoyed! However I am also full of anxiety and fear of the thought of growing a human inside of me and raising a child. I LOVE children and have always wanted to be a mom and feel awful that I am so terrified of what is to come. I know it will be an amazing journey. I just wanted to make sure that completely freaking out is normal 🙊🙈
