We saw a HB at 6w2d with Niki but only saw the sac and yolk with this one at 5w3d. We later saw a HB and foetus at 8 weeks.

Foetal Pole grows into your baby, yolk sac I am assuming is the embryonic sac the bub will live in until birth, the Yolk is the placenta in its early stages.

Congratulations and best of luck with your pregnancy
