Doubling time slowing?

ngolden · 07-08-2007, 11:41 AM

Here are my betas

12dpo 100
15 dpo 465
18 dpo 1338 (different lab)

My earlier betas were doubling every 32 hours and now my last two are only doubling every 47. Is this necessarily a problem? Any experiences?

Something similar happened with me. My first beta doubled very quickly, my second was slightly over 48 hours. My RE said not to worry, that it can take up to 3 days to double. Besides, you are still doubling under 48 hours! You are pg. Congrats!

acceptable doubling is once every 72 hours, so you are TOTALLY OK! Also, as the number gets higher the doubling rate slows down. Try not to worry!!
