Is it okay to have a baby shower at 20 weeks??

Alexis • Expecting our sweet baby boy in April.💙 I thank God for giving me such a wonderful opportunity!
My husband's family is throwing a baby shower for us on November 19.. I'll be 20 weeks and 5 days on the day of the baby shower. I've been told that it's too early for one but we will be driving 8.5 hours since his family is throwing it for us.. and I don't want to wait til I'm further along and travel that far...
