In the sixth week, the fetus is still tiny, measuring approximately 3.1-6.3 millimeters, roughly the size of a grain of rice or pomegranate seed.
This week, the neural tube at the back of the fetus closes. The brain and spinal cord start to develop from it. The fetus begins to resemble a tadpole because of the presence of something like a tail (which will develop into the spinal cord).
It's essential to visit the doctor when a positive pregnancy test result appears to ensure both your health and the health of the pregnancy.
