I’m sorry if this is the wrong board.

So my sister just found out She was pregnant and had her first ultrasound, she should have been 8ish weeks but they were measuring 5weeks. I am looking for any words of advice on what to say to her, anything to do to help comfort her in this time. They were extremely excited but she’s asked for some space right now and im just trying to figure out what to say/do if there is anything to help her.
