Thirteen weeks of pregnancy, which is one week over the third trimester of pregnancy. At this time, fetal development is almost complete and the sex of the fetus can already be identified with an ultrasound examination. However, because the fetus is relatively small, most pregnant women cannot yet see the pregnancy from the surface. It usually takes five gestational months of pregnancy for the pregnancy to become apparent from the appearance. A little over two months into pregnancy, pregnancy vomiting begins to appear. More than one week into the third trimester, when there may still be pregnancy vomiting, or the pregnancy vomiting may have ended. Touching the abdomen can reveal that it has become significantly harder and larger, however, the abdominal bulge is not too obvious, but an ultrasound examination can clearly reveal the fetal limbs.
