5 Weeks, 5 Days. 25,473 HCG Level?!?!

Kristen • Marine Wife // Audiology
So, in this sonogram, I was 5 weeks, 5 days. Which was Monday. They did my beta and my hcg level was 25,473. Which is crazy high. Does anyone know why it could possibly be so high? Im not worried, im just curious. I miscarried in this past December, but when I was 5 weeks and 5 days back then my hcg was only 387. Crazy difference. Any ideas? ❤️
