Doctor's answer:

Hello, molar pregnancy is divided into complete molar pregnancy and partial molar pregnancy. Complete molar pregnancy is usually easily detected through ultrasound, but partial molar pregnancy may not be accurately diagnosed. It is recommended that you combine color Doppler ultrasound to determine if there is a possibility of molar pregnancy, and further evaluate based on your symptoms, HCG hormone blood tests. If necessary, a pathological examination after curettage is required for a definitive diagnosis. In addition to ultrasound, it is recommended to perform a urine pregnancy dilution test. If the urine is strongly positive even after being diluted 500 times, it can be confirmed as a diagnosis. Moreover, there is generally no need to worry too much. If all the above tests are normal, it is basically possible to rule out the possibility of molar pregnancy. If you are pregnant, it is important to maintain a good mindset, which is also beneficial for the baby.
