Okay so. Just looking for some possible hope.. I don't have periods but <a href="https://play.google.com/store/apps/details?id=com.glow.android">tracking ovulation</a> puts me at 7 weeks. So I thought. My Dr. said hcg only rises with fetus growth. But my question is.... how is my hcg at 4000 but the ultrasound is showing only a blastocyst? Which a blastocyst is at 4 weeks or less.. and 4000hcg is around 5-6ish weeks... how does that even work? How does the hcg rise higher than the growth of the fetus when hcg shows the growth?? 2nd hcg results are tomorrow.. we will know more then. We're looking at our possible 3rd miscarriage since August. 😟🥺😔 just trying to make sense of it...
