Patient's question:
Doctor, hello. I am 41 days pregnant and had an ultrasound. The doctor said the fetus is very small, and there seems to be something on top. I'm not sure if it's twins or something else. I'm very scared and worried. Doctor, could that thing be a tumor or something else? If it is a tumor, can the fetus still be kept?First follow-up question: When should I have another check-up? Will frequent ultrasounds affect the fetus? I also want to ask, will the two sacs of twins be of different sizes?
Doctor's answer:
Hello, it is generally believed that fetuses within the first 18 weeks of pregnancy should not undergo an ultrasound, especially in the early stages of pregnancy. Of course, exceptions exist for special circumstances, such as cases of vaginal bleeding, where an ultrasound is necessary to determine whether the fetus is viable, whether the pregnancy can continue, and whether there are any abnormal pregnancies or molar pregnancies.If you do not have symptoms of vaginal bleeding or abdominal pain, and are not experiencing any discomfort, it is recommended that you undergo an ultrasound examination around the 50th day of pregnancy. This can not only confirm an intrauterine pregnancy but also clearly observe the condition of the embryo. By assessing the presence and activity of the fetal pole and primitive heart tube, you can determine whether the embryo is developing normally. This period is also the best time for you to have an ultrasound examination.
