Pregnant with twins, 1 fetus does not develop, is it damaged?

Ask
Hello doctor! On September 26, I had bleeding, so I had a fetal ultrasound and discovered that I was pregnant with twins, 2 bags of equal size, 1 bag with a heart and 1 bag without a heart (with a yolk), the size of the 2 fetuses is similar. . At 6 weeks, I was threatened with miscarriage, so I was hospitalized that day. Today I went to have an ultrasound again, 1 fetus has a heart that develops into 6 weeks 3 days, and the other fetus still keeps the same size and has no fetal heart, the doctor will re-examine it next week. So the doctor asked me if the fetus is not developing, is it damaged? I would like to thank the doctor.

Hello! According to the doctor's understanding, this is a case of twins, 2 placentas (2 separate gestational sacs), 1 fetus has no fetal heart. Thus, only 1 fetus is left to develop.
However, to be able to accurately diagnose and give appropriate advice about your condition, you can go to reputable medical facilities or hospitals under Vinmec Health System to be examined by a doctor. for in-depth assessments.
