7.5 Week Fetus
Fetal Development

The hand plates become present this week, and the baby is about 7-9 mm CRL by the end of the week. The genital tubercle is present, but you can't distinguish girls from boys by sight at this point. Nasal pits are forming.

Your baby will actually go through 3 sets of kidneys, very rapidly as they develop during this period. This week the second of such sets will form.

With a transvaginal ultrasound, one study shows that 100% of the ultrasounds will be show a fetal pole with heart motion.
