When to announce pregnancy to work while working from home?

La

I’ve been trying to decide when to announce my pregnancy to work. I’m due Oct 12. Not showing yet, and due to C-19 I’m working from home for at least a month or two, so no real reason I need to announce it yet. I haven’t posted on social media so it’s not out for anyone to see. Anyone else on the fence about how soon to announce to work? Curious to know your thoughts!
