That bubble attached to the speck (baby) is the yolk sac. Good luck.

So how does the ramzi theory work? How can I tell where my yolk sac is?

Girl

When you are 6 weeks, baby is living off the yolk sac, placenta isn't fully developed till 12 weeks

No one knows ramzi theory?

How can I tell where the placenta is?

I'm 6 weeks and this was taken vaginally.
