Mom, I'm like a raspberry (16mm)

This is a pivotal moment - I stop being an embryo and become a fetus because all major organs are now present in basic form. My heart beats at 150-170 beats per minute and has fully formed chambers and valves. Fingers and toes begin to separate from the plates, though they're still connected by membranes. Eyelids form and completely cover the eyes, which will remain closed for the coming months. External genitalia begin to differentiate under hormonal influence, though sex isn't yet determinable. My tail disappears. Ossification begins - the first bone centers appear in ribs and vertebrae.

Remember mom, every child develops at their own pace and has their unique timeline. If you have any doubts about my development in your belly, consult with a doctor.
