Annoucing an edd?!?!?

ma

Okay, so funny questing but I'm thinking wayyyy ahead of time but we've been trying since the end of June and everytime I calculate my edd it's always the 29th, 30th or 31st. If this month is our lucky month our edd will be June 30th. How would I announce which month my baby due like the picture posted below. Would I do due June 2020 or July 2020 since it could come either month?!? I posted an example below so you know what I'm talking about lol.
