Patient's question:
Had two retained miscarriages, the last one in January 2016. Menstrual flow is light, with a cycle of 3-4 days. The last menstrual period was on July 11, 2016, and menstruation has not occurred since. Urine test shows not pregnant.Doctor's answer:
Hello: Generally, there is an error between the gestational age detected by ultrasound and the gestational age calculated from the time of the last menstrual period. This is normal, as the ultrasound is based on the size of the fetus's development for the calculation.Advice: Therefore, based on your ultrasound results from June, the fetal development should be normal. I suggest you don't worry. As long as your menstrual cycle is regular, the pregnancy duration is still calculated based on the last menstrual period. Thus, on July 11th, it would be the 12th week of pregnancy.
