It's still very early. Some people scan at week 6 onwards but the best is to see from week 8 onwards since its clear already. I had my first scan at week 8 :)
Yes it's probably too early. Doc will ask u to go back for a scan again a few weeks later. That's when we can be sure if there's a sac or not.
Hi there, it’s too early to see. Wait awhile more and you can see more stuffs
