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.
Welcome to ehealthforum,
It is possible to see a mild drop in the HCG levels if one of the embryos did not survive. If pregnancy gets confirmed, go ahead with getting serial HCG levels estimated. Doubling up of the hormone levels in 48-72 hours will show that pregnancy is going on smoothly. If levels are not adequate, then external hormonal supplements would be considered to be started to help you in preventing miscarriage/threatened abortion. A transvaginal scan done at 6-8 weeks of gestation will also help to confirm fetal heartbeat, gestational age of fetus/baby along with fetal viability. Visit your doctor/gynecologist for further evaluation and assistance. Be in regular monitoring and follow-up with your treating doctor/gynecologist and report any new/abnormal symptoms immediately. Take adequate rest. Drink plenty of water. Maintain healthy diet.
