They're normally pretty accurate but it is possible to be off by a week or two as well. If your last period was at the end of January you would have ovulated a week or two after that putting conception in or near Febuary. Due dates and conception dates are usually not important unless you're trying to figure out paternity. If this is the case, you would be best off with a DNA test.

Ultrasounds are more accurate than a HCG beta test... When I had my bloodwork done in Urgent care at 6 weeks it was saying I was 4 or 5 weeks... But the ultrasound showed that I was 6 almost 7 weeks.... So Ultrasounds are more accurate than blood work.

Why did you have a scan after 15 weeks.did you have a dating scan at 12 weeks.this is what they do in the uk.I agree scans can be off by a week or so.due to them not knowing exactly when we ovulated.i would agree conception occured during febuary.the slight bleeding you had in feb was most likly implantation bleeding.this isnt common,but does happen.
