First Baby, First Shower, TOO LATE?

Cherina
Due to graduations and birthday parties my shower got moved back to May 17, almost at the 37 week point! I have had an AMAZINGLY pregnancy thus far no sickness, minimal pain, and working more than ever before (happily), however I am very afraid that this date is too late to have a shower? What if I'm too big or tired? What if baby comes too early? Or what if I don't have time or energy to organize the nursy as I wabt. Second and third time moms please help me out?
