I agree with the other girls. Ask for a HCG blood test at your GP. The value should double every 2-3 days. Early pregnancy is definitely a scary time. I didn't have morning sickness until week 6 and haven't had sore (.)(.) at all so don't go by symptoms of pregnancy. Oh and HCG can't accurately tell you how far along you are, a doubling every 2-3 days tells you that things are progressing as good as they can be in the early stages.

Good Luck
