Size of fetus
After reading many books and other info on fetus development, all of them indicated that the fetus should be 35mm long at 8 weeks and 65 mm at 11 weeks. I had my first scan @ 8 weeks and the little one was only 20mm and at 11 weeks only 45mm...should I at all be concerned about this?

The correct figures are 45 mm at 11 weeks and 16 mm at 8 weeks, so your fetus is spot-on.
