WIBTA for being angry at my dad for sharing my pregnancy news without permission?

I (30F) am currently in my second trimester with my first pregnancy to reach this stage (I had a previous miscarriage). When I visited my parents recently, my dad specifically asked when I'd be telling his side of the family about the pregnancy. I told him I'd share the news when I was ready and when I could tell them in person.

A week later, my sister texted me saying that all my extended family already knew because my dad had told them whilst they were visiting a sick relative in the ICU.

I'm really upset about this for several reasons:

1. He literally asked me about my timeline and then completely ignored what I said
2. He chose to share happy news whilst everyone was gathered around someone who was critically ill in hospital
3. Given my previous loss, I'm being very cautious about who knows - only immediate family and close friends are aware, and I wasn't planning to tell anyone else until after my next appointment

I know he was probably excited and meant well, but I feel like he completely disrespected my wishes and chose the worst possible moment to share the news.

WIBTA if I hold a grudge against him for this and refuse to share any future pregnancy-related updates with him? I'm considering keeping him out of the loop for things like the gender reveal, baby shower planning, or any complications that might arise. Part of me thinks I should just let it go since it's done now, but I'm struggling to trust that he'll respect my boundaries going forward.
