As Bg said, it's not the start amount that matters, it's how it doubles.

Sometimes I think all these bloodtests just do our head in. I know, I did them too. Does getting bloodyests help you more than not getting them? It's not like knowing hcg levels can change the outcome. Sometimes ignorance can be good for our sanity.

Try not obsess. I know it's hard after a loss though. If you do want to obsess, I found Beta Base was a good source. Just remember, once hcg gets over 6000, it becomes an inaccurate measure of viability.
