Hello, doc. My wife has gone for ultrasound on six weeks and two days of pregnency, as said in the ultrasound report. It is said that a well defined rounded fundal implantation intra uterine gestational sac is seen. But, no definite viable embryo is seen. Further, it is stated that a well defined yolk sac is noted. The report also says that MSD: 1.92 cm: corresponding to 6 weeks and 2 days and uterus is bulky with normal myometrial echotexture and no myoma is seen. Please help me in understanding these statements of the report. My wife is 27 years old and has 62 kg of weight.
