Repeat US: AT 7 weeks of gestation, the fetus is approximately a quarter of an inch in length, about the size of a pea. On US, several structures can be seen and at this age the heartbeat can be detected. It is too early to see formed blood vessels reliably. Repeat the US since it is operator dependent, when the fetus is a few weeks older. Thrombophilia can be a cause of fetal loss, but usually later
