Talk to experienced gynaecologist online and get your health questions answered in just 5 minutes.
At six weeks by your last period, a gestational sac without a visible yolk sac usually just means the pregnancy is a little earlier than your dates suggest, since the yolk sac is normally the first structure to appear as the sac grows. This alone doesn't point to a chromosomal problem; those aren't checked through this kind of scan at all.
Next Steps
A repeat scan in one to two weeks is the usual way to confirm your dates and check the pregnancy is progressing well. Keep taking your folic acid and progesterone as prescribed in the meantime.
Health Tips
Please discuss this with your obstetrician in person, so your dates and the pregnancy's progress can be properly assessed.
