Baby shower at 36 weeks ? Good idea or no

I'll be 30 weeks monday , but I plan on doing baby shower 14th of Sept. Due to financial reasons. I just need some time to save up and I want to be a little bit bigger. My doctor has told me I have a small pelvis and if my baby girl gets to big I may not be able to push and he would have to do me a csection. With that being said is it safe to do it when I'm 36 weeks or should I plan it earlier just in case.
