announcement opinions please!

I have two healthy boys. 7 and almost 2. I had a miscarriage at almost 15 weeks in November last year. Just experienced a recent miscarriage at 5 weeks this past March. Not trying , we are pregnant again 🎉 my husband wants to wait to announce to anyone including family until it's after 13 weeks. I disagree because we'd need support if it doesn't turn out as a happy ending. Any opinions?? Of course I wouldn't announce anything without my husband agreeing
