The baby is not a foetus yet. The 12 week scans always show a foetus. Never will an 8 week scan show a foetus, the pregnancy is 9 months because it has to grow.
An unborn baby that is less than 8 weeks old, is an embryo, after this it is classified as a foetus.
Depends on how you feel, there are no set rules on it.
6-8 wks
It takes 40 wks for a foetus to reach full term maturity in single or multiple births. Multiple births are induced earlier if there are problems.

A Foetus is formed by the growth and development of an embryo. A Foetus is an unborn baby in the uterus in the later stages of development (after 8 weeks till birth). A Foetus is also multicellular. The body features of developing baby can be identified.
If you have had no cramps or spotting it is unlikely that you will have lost the baby between 6 and 8 weeks.
