Patient's question:
For over a month, the ultrasound showed one fetus, which was normal. After a week of follow-up, it showed two fetal buds, and the doctor said it was monozygotic twins. Another week later, it showed one again, and the data was also normal. What is going on? Could the disappeared fetus have any negative effects or long-term consequences on the current fetus?Doctor's answer:
Hello, both twins or multiple fetuses may experience the phenomenon of poor gestational sac development. It needs to be considered whether there is one poorly developed gestational sac or the possibility of a stopped development based on the number of days you are currently pregnant. Since multiple fetuses require higher nutritional components than single fetuses, if there is an uneven distribution of nutrients, it is more likely to result in one poorly developed gestational sac. It is recommended that you have another ultrasound in a week to observe the development of the other embryo and determine whether it is poorly developed to make a decision on handling. You can also take a few more days to rest, eat well, and see if there is any improvement. Wishing you and your baby good health.
