these are so cool! I showed a couple to DH and he got really excited- he said it made the whole thing seem more "real"

I just noticed this: All ages referenced to fertilization, not last menstrual period. One month = 4 weeks.
So I am 10 weeks, but the 8 week fetuses are what my baby looks like.. right? because the EDD adds those 2 weeks between last period and ovulation/fertilzation
