Just wondering how safe it is to have extra ultrasound scans during pregnancy.
I am 17+2 weeks and wanted to have a private gender scan carried out this weekend. Three weeks later I am having an NHS one. Want one done earlier as am such a worrier that don't think I can wait over a month to see if everything is ok!!!
But can extra scans cause birthmarks, or birth defects - are they generally safe?
Thanks
