Re: beta 170 at 14 dpo
With ds, my hcg was 75 at 16dpo. His was on the low side, but your is perfect. Often as a general rule, there is more confidence in a pg if the beta is close to 100 at 14dpo, and you are well over that number.
With this pg, my beta was 204 at 14 dpo &my RE commented on how high it was. Yours isn't much below mine, so it sounds like a great number to me!
