High hCG levels after a 2 blastocyst embryo transfer

Hello, I’m totally confused and freaked out! On May 22nd I had 6days old frozen blastocysts transferred (2). On Friday, June 8th, my beta was 461 and today, June 11th was 853! I am freaking out! Please let me know if I am within the normal ranges..

Hello Dimitra,

Considering that you had two embryos transferred, you may be pregnant with twins. hCG levels of between 850 and 20800 mIU/ml indicate 5-6 weeks of pregnancy. But considering that you had the embryos transferred on May 22nd, you’re not 5-6 weeks pregnant, that’s why your levels are considerably elevated.

Unfortunately, you cannot get a confirmation of a multiple pregnancy until you go for the first ultrasound scan, which will be able to confirm that you are indeed pregnant with multiples.

I hope I have been able to help,
