Answer
Hello,
With the question “Is it okay to have an embryo at 6 weeks pregnant? , please answer as follows:
Embryo is formed in the 5th week (from the time of fertilization) and develops for 6 weeks before being called a fetus. During the sixth week, the neural tube along the back of the embryo closes, the heart begins to pump blood, and the inner ear and jaw arch begin to form. The embryo begins to bend in a C shape, and the sprouts of the upper and lower limbs appear.
Normally, after a woman is about 5-6 weeks pregnant, the fertilized egg will have an embryo and a gestational sac (where the fetus develops) about 18mm wide. In the case of an empty ovum, the gestational sac is still forming and developing, but there is no embryo.
In the first weeks of pregnancy, when ultrasound will show a gestational sac from 19 - 36 mm but no embryo. If the embryo continues to not be found at 8-13 weeks, it can be concluded that it is abnormal and just an empty gestational sac.
Therefore, 6 weeks pregnant, ultrasound has not found a gestational sac, you should go to a medical facility for examination and ultrasound again in the next week of pregnancy.
