How many weeks would be a good time for a baby shower?

My baby shower for my first born was when I was 36 weeks.. He decided to come the day before my shower, so needless to say I missed it entirely. I'm pregnant with boy/ girl twins, and will be 30 weeks by the time we'll be having it.. Nervous since twins arrivals are unpredictable.. How far along will you girls be by the time of your shower?
