SUA diagnosed at 22 weeks

I had a second anomaly scan today at 22+4 because at my first one she was moving too much for them to see some things. They said everything with her looks absolutely fine, except she has a single umbilical artery and will need growth scans throughout the pregnancy. They told me not to worry, so i made the mistake of googling it thinking it would be reassuring but instead i’ve seen loads of scary things about it and now i just feel panicked😩 Does anyone have a positive stories or advice if they’ve had this in their pregnancy?
