Second child anxiety?!

It’s hitting me now that I’m going to have another baby in 35 days or less... Did I space it out enough between children? Did I give my daughter enough in the 2 1/2 years she was an only child? Will I be able to love my son as much as I love her?! We wanted another for so long and now I’m freaking out! Is this normal? I cannot be the only one who has felt like this.
