Grandma ruined announcement ?

So long story short I got married three years ago and didn’t tell anyone just got eloped. Everyone was mad because I didn’t invite my grandma which in reality I didn’t invite anyone. So when I first got pregnant this time my mom said I should tell her because of what happened when I got married cool so I told her but I also told her DONT TELL ANYONE. It’s my 3rd and I wanted to wait. Well thanksgiving comes around and she’s just telling EVERYONE. I’m really disappointed because I wanted it to be my own announcement but it is what it is. So I ended up announcing early. This week I announced at 10+4 wayy earlier than I wanted but am I in the wrong for being upset with her? Like I get that you’re excited but it was excitement for me too. 😔
