In the seventh week of pregnancy, the embryo should already be seen inside the gestational sac and, in addition, it is very likely that the embryo's heartbeat can also be heard. If this is not possible, the gynecologist may suspect that an anembryonic pregnancy has occurred, in which the gestational sac is seen but the embryo is not inside because it has stopped its development too early.
I have had an ultrasound in week 7 of pregnancy and nothing is visible, is there anything wrong?
