When to announce on social media??

Hi everyone! So I’m almost 8 weeks pregnant. We told our close family a couple weeks ago that we are expecting our third. Our boys are 6 & 8 years old and we’ve been trying for this baby for nearly three years so to say we are excited is an understatement! I just did the SneakPeek clinical version and it came back saying we are having a girl! We are over the moon. My question is, is it too early to announce on social media? I know it’s a personal decision but I’m just wondering what other people are doing. I also want to say, on my social media, I consider everyone to be a friend. I just didn’t want to post and have anyone think that we are crazy for announcing so early.. is there a rule for this?
