3 months myth

It's not a feng shui/pantang thing actually. It's just that the first trimester is known to be unstable, so some couples prefer not to share the news until completing the first trimester. Think of it as, you'll only share good news when it's totally confirmed right. We didn't even tell our immediate family members until we completed the first trimester and they were very understanding of it. Their response was, "Are you announcing now cos you just finished the first trimester?" It's actually well understood and acceptable.
