Is it wrong to have a baby shower early?

Savananah
I'm 13 weeks 1 day along, and I've been planning on having my baby shower the last weekend of November, because it's before winter and before Christmas and New Years. I'll be 6 months the Wednesday before the baby shower, but my sisters think I should wait longer, but I don't have any friends, and barley any female family members, so I wanted to have it at a time where people would actually be able to go, is it bad to have it this early?
