Cancel the baby shower?

I didn't realize that I set my baby shower way to close to my due date. Shower is on 3/11 I'm due 3/23 I'll be 38wks if I make it to the shower. I'm wondering if I should cancel it? I have the venue. The decorations have been ordered. I'm just really worried she won't stay in until then. This is my 2nd and I'm already as big as I was at the time I gave birth with my 1st. Has anyone else had a shower this late?
