Pediatrician*** and maybe look into birthing and breastfeeding classes if those are your plans.
If your wanting a baby shower, start focusing on that and once you have all your things you can start nesting! Also as the previous person suggested, look for pedi
Pray for peace of mind, I know biw you feel almost in the same boat. I've done the pamper buying here and there, also little clothes for when I give birth and also when we're home. You'll need a carseat so they let him come home and a baby bed if you don't want him to get accustomed to sleeping with you. Baby blankets, booties, and hats to keep warm. Breast pump I was told is given to you if by chance its not Im getting one from walmart when i leave the hospital. Baby bag of course, you can use that as your overnight bag in the hospital so you don't have alot to travel with. Of course before the hospital time you do have a baby shower my sister is planning mine because this is my first also lol. You'll do great, no mess ups or worries.
Start looking for a pediatrician for when your child is born, you and your baby will be covered.
