I'm pregnant with my 4th child and due to have a routine US exam on Friday, it's a 21 week fetal anomaly scan (I'm in the UK). I'm actually really going off the idea of getting scanned so frequently, I'm just not sure they are necessary but I know if I say to my husband or family that I don't want to go to the scan on Friday there is bound to be a huge argument as they will say the scan is necessary and I'm being unreasonable. TBH I'd love to go UC as well but there's no point even getting in to the argument that would cause.
Thoughts? Any arguments for or against getting the scan?
