###Human: One of the twins got miscarried. Are my reports worrying? ###Assistant: Hello. How are you doing? What you had, in the beginning, was a vanishing twin syndrome. The healthier of the twin survived. The baby which disappeared mostly had some genetic problem, which was not compatible with life. The brown discharge you had was implantation blood. Altered blood is passed without any pain. As your NT scan was normal with normal appearing NT and nasal bone, this nearly rules out chances of Down's syndrome. Single soft tissue marker at this time is not significant. This could just be an error of measurement of the sonologist. Your age is also of low risk. If I may suggest do have a 3D scan to rule out the anomaly of the baby. There is really no need to worry, with everything in low risk, why are you worried about one factor, which could just be an error? Do have a second opinion 3D scan. It will be normal. Hope I have clarified your query, do write back if any more queries. All the best. For more information consult an infertility specialist online -->
