Inconsistency in gestational week and embryo size refers to the inconsistency in the number of weeks of menopause and the development of the embryo, which may be due to delayed ovulation, late conception, late implantation, etc., and usually has no adverse effects. When the gestational week and the size of the embryo do not coincide, as long as there is fetal heartbeat and fetal buds, it means that the embryo is better developed. Smaller embryos may be caused by delayed ovulation, late conception, late implantation and so on. You can review the ultrasound and progesterone and human chorionic gonadotropin to determine the actual gestational week through a combination of these tests. If the size of the gestational sac and embryo are different, then during pregnancy, you must pay attention to balanced nutrition, meals should not be partial, you can eat more fresh fruits, vegetables, meat, fish, eggs, dairy and other nutrient-rich foods as appropriate, which is beneficial to the baby, in addition to be sure to do a good job under the guidance of the doctor’s pregnancy test, and timely observation of the development of the embryo.
