Would this be a good time to announce were pregnant (if we are)

We will be going down and seeing my family for a family wedding next weekend (hear me out, announcement not at the wedding) and the day after the wedding were planning on meeting up with all our family for a BBQ. We don't often see my family (as they're a state away) and we'd love to announce in person... Is this too close to the wedding? It's both of their second weddings, but that doesn't make it any less special for my uncle and his bride. What do you think? It'll also be the first great grandchild on my side of the family. First baby of my generation. What do you think?
