Bfp at 38yrs with #3 and scared😬😬

Just found out I'm prego with baby #3 and I'm really terrified to tell hubby and family, this will be his 4th kid and all of them are boys. Hubby and I have talked of having another because I would like a girl and I've always wanted at least 3 kids but lately he's been adamant about not having anymore, but he hasn't made the time to get a vasectomy and we use the pull out method. Any advice or encouragement on announcing it to my hubby and family?
