I'm 39 & 6 weeks preg. W/ twins. How concerned should I be about vanishing twin syndrome? What should I expect at my visit in 2 weeks. I'm really scared

Worrying will not. Help the matter any. Vanishing of one of the twin is being recognized more often due to the common use of ultrasound in early pregnancy. I understand your being concerned, but that will not affect the outcome. Please see this site for information on this topic. Http://emedicine. Medscape. Com/article/271818-overview.
