When should I have my baby shower!

I'm 22 weeks as of right now, we're  due on June 29. Since this is my first baby I have no idea how to plan a baby shower or let alone what month to have it... Going off subject who here is nervous about this Zika Virus since summer is right around the corner I'm freaking out. Any ways back to my subject lol (mommy brain) I already have a theme for the baby shower I did not want to the traditional baby shower have all blue and blah blah (having a boy 😁) I'll give you guys a hint on the theme I've chosen ☺️
