You're 19 weeks pregnant and your baby is now about 6.5 inches long (crown to rump) and weighs about 7-9 ounces.
The skin is wrinkled and there's still not a lot of fat underneath, but the reddish color of the skin is starting to disappear.
This is a crucial time for the development of the baby's senses. Your baby's brain is indicating which areas will specialize in smell, taste, hearing, vision, and touch. The nerves that connect the muscles to the brain have grown into place.
The kidneys continue to make urine and the features of your baby's heart should be visible during an ultrasound.
The hair on your baby's head continues to grow and the baby's arms and legs are in proportion to each other and the rest of their body. Their tiny little feet are about 1 inch long...can you imagine that little footprint?!
You should be feeling more than flutters by now, but if not there's still time for the big movements to "kick" in!
The genitals are very distinct now, you should be able to find out if it's a boy or girl. Unless your baby is shy and hides the private area, but ultrasound techs have been known to be wrong on occasion.
With my 2nd son the tech told me that the easy way to detect that it's a boy is to look for the turtle. From a side angle (not from underneath) the baby's sac resembles the body of the turtle, and his little pee-pee resembles the head of the turtle.
