Bomb dropped about my shower

Avery
My mother and I agreed to have my baby shower at 32-33 weeks. She even booked a venue and a date. Today I get s call from my father saying that they are no longer going to come back early from their six week vacation so the shower has to be a MONTH later. This shower is going to happen less than three weeks from my due date!! :( I am freaking out!! :'( I might miss my own shower if I go early!
