<s>[INST] Hi, I had my last period on December 14th, and my husband and I had sex on December 26th. I have all the early symptoms of pregnancy a positive home test on January 12th, an positive in office test on January 26th but went for an ultra sound yesterday and should be 7 weeks 2 days and all they say via a transvaginal ultra sound and a regular ultra sound was the gestational yolk sac, we saw no baby or heart beat, With my other children we had ultra sounds at 7 weeks and saw the baby and heart beat. I have had no bleeding or cramps or anything it has been perfect so far, just wondering what could be up? I don t know if it matters but my cycles are staggered every 25 or 28 days from month to month and the one in December on the 14th was only 23 days from the last one. I have yet to hear from my doctor and I am freaking out, I have had two miscarriages int eh past one at 9 weeks 9 years ago after we had seen the heart beat at 6 weeks, and one two weeks after I found out I was prgnant in 2009. I just do feel the same way is it possible everythign is fine and the baby was just hiding or somthing? [/INST] No this is not a viable pregnancy.  It's missed abortion.  But to be 100% sure you can repeat scan after a week. If no cardiac activity then go for termination of pregnancy. </s>
