When someone tells me that they or their partner are pregnant, my typical response is "Congratulations!"
But I have found out that this remark is not always appropriate- notably when the pregnancy is unplanned. Sometimes I am informed about the pregnancy via text or online chat so it is harder to get a read on their feeling towards it. In some cases I do not know the person very well either so I do not know if I would expect them to be excited or distressed about the news.
I feel awkward thinking about asking "Was the pregnancy planned?" or "How are you feeling about it?"
Specific examples:
"So I'm pregnant." / "Oh, congrats!" / "No, not good..." / "Oh..."
"Just found out that I'm pregnant." / "Oh, congrats!" / "I... I'm not sure what to do."
"Oh yeah- (partner's name) is pregnant." / "Really? Congratulations!" / "..." / "..."
"omg guys im pregnant" / "congrats!!" / "no I'm SO F***ED"
In all my personal cases I was not informed prior that the person/couple were "trying for a baby".
What is generally a polite or appropriate response when someone informs me of their or their partner's pregnancy if I can't get a read on their emotions?
Not sure if it is relevant for context but I am a 24 year old living in America.
