Announcement issue?

So, over the next few days were letting the rest of our families know. And in Valentines day I'm announcing publicly.

I'm from a small small town, my work is very tight knit, but I'm wondering if I tell work first?

I have a few co workers on facebook, but they'll be at work and wont see it until that evening or whenever they go on FB next. So should I tell my co workers and boss myself or let them find out from me announcing?

I dont work fridays, which is the day I'm announcing, but im thinking of taking my daughter for a visit there anyway so I could tell them then? And post online before if after that? 🤷🏼‍♀️

Does it matter, am I thinking Into this too much? Lol
