I had the same thing happen to me today, I am so confused and scared? What was your outcome?
Im really sorry for your loss.. It is very possible for your embryo to stop developing and you not pass it right away.. my first pregnancy I had a scan at 12 weeks and i was only measuring 7.5 weeks.... I hadnt showed any signs of passing it ... I had a d&c a couple days later... It can definitely take your body time to recognize the pregnancy has failed because HCg continues to be in your system.... I was still having symptoms and testing positive after that 4.5 weeks because my HCg was still around 5000.... dropping slowly..
I really hope your dates are wrong
I hope your dates are wrong, also. In answer to the question about the body not passing the embryo, when I had a natural miscarriage, it took 4 weeks for any bleeding or anything to start.
