19 weeks and counting

I'm currently 19 weeks with my first daughter. I have a 11 year old and a 6 year old.  Debating on if I should have a baby showe. My family wants me to, but they also want me to drive 8.5 hours to do so. I would rather have one here especially since I am always going to the dr. 
I have tried to complete baby registry's but I can't think of what all a baby girl would need. I feel so out of my element here. M excited for her to come out ( mainly so I can have my body back).  But then I think I'm almost halfway through and haven't bought anything. 
All moms please help and give ideas.  She does have a name at least. Nova Elyse will join us on September 21, 2017
