I have a question regarding fluctuating HCG levels. I just did a FET transfer with two embryos and my first hcg level at 9 days post transfer was 476, my second was 817 two days later, and then I got a call with the results 4 days from the 817 my hcg had dropped to 730. They called to tell me I was miscarrying but that they wanted to recheck the next day to confirm. I had accepted the fact that I would miscarry, and then 24 hours later my level had risen to 1001. I know that hcg levels should double every 48-72 hours at least and that any drop means something is not normal. My question is that could it be possible to see this drop with vanishing twin syndrome if both embryos took, or is that just hopeful thinking.
Thanks
Ashley
