What is this? A baby for ants?

That is a piece of rice or something. And if it is a fetus, that is one sick mother.

That is the representation of a zygote (the first stages of a baby before embryo and fetus)

Gametes fuse in to a zygote, but it's all microscopic. From fertilization, you get a bunch of cell divisions as the zygote implants into the uterine wall. A few days later, the cells start differentiating and form a blastocyst, which is still microscopic. After a lot of cellular multiplying and more differentiation, the blastocyst becomes an embryo.

This thing in the picture is maybe the size of a five-six week old embryo. It won't be a fetus until week 10 of her pregnancy.

Thank you, thank you very much.

that's when the baby is due to arrive
