Baby shower at 22 weeks?

So one of my sisters lives in Cali, and is road tripping to Jersey to visit me in July. And my other sister lives in Georgia and starts boot camp in August. And my other sister lives her in Jersey with me but will be moving to Cali at the end of July. Also my SO's family is going to the Dominican mid July and won't be back til mid August. So the only opportunity I have to have everyone here is early July, thinking the 8th or 9th. I'll only be 22weeks. I'm currently 18weeks... and still not showing. I feel like I won't have much of a tummy, and idk why but I have it in my head that I want to look preggers for my pictures. Sigh... is 22 weeks too early for a baby shower?
