Unique girl themes?!

Victoria • I`m a 34 year old married woman! I`ve been with my hubby for 10 years and we have a beautiful 5 year old little girl and a 2 year old little girl! We’re TTC #3.
Basically the whole pregnancy I've thought I was having a boy! So I've planned everything around a boy!! Thank the lord I didn't get anything yet! We found out yesterday it's a girl and now I'm completely lost as to what to do for a nursery! Help!! Any cute ideas?!
