Introduction
A pregnant woman's gestational age is usually calculated from the first day of her last menstrual period. A pregnancy of one and a half months typically corresponds to approximately 6 weeks of gestation. At one and a half months pregnant, the fertilized egg has already implanted in the uterus and embryonic development has begun. In the early stages of embryonic development, the embryo is typically only 2–3 mm in size, which is too small to be measured by a routine ultrasound examination.
Intrauterine pregnancy usually refers to a normal pregnancy in which the fertilized egg implants inside the uterus, rather than outside it. At one and a half months of gestation, the fetus is typically about 2–3 mm in size. The specific analysis is as follows:
A pregnant woman's gestational age is usually calculated from the first day of her last menstrual period. One and a half months of pregnancy generally corresponds to approximately 6 weeks of gestation. At this stage, the fertilized egg has already implanted in the uterus and embryonic development has begun. In the early stages of embryonic development, the size is typically only 2–3 mm—too small to be accurately measured by routine ultrasound examination. As the pregnancy progresses, the embryo gradually increases in size and becomes visible on ultrasound. Because each woman's pregnancy is unique, the exact size of the embryo during early pregnancy may vary.
If you are one and a half months pregnant and would like more detailed information about your pregnancy, please consult a doctor for professional evaluation and advice. Ultrasound examinations are commonly used to determine gestational age and assess embryonic development.
