Yes there are those with a lower hcg level at 14dpo, but it is likely above 25 and will register on a hpt.  So those who say they got there's after 14dpo, got their ovulation all wrong.  Many women assume they have 28 days cycles and o on cd14.  So when they don't get their bfp til 14 or 15dpo, its usually because they didn't really ovulated til cd17 or something and they are actually getting their bfp on 11dpo.  KWIM.  With IVF, the common "known" is if you do not get your bfp by 7dp5dt you are 95% out.  That is 12dpo.  Most girls will get it on either 5, 6 or 7 dp5dt -- so 10, 11 or 12dpo.  That is the norm -- so when people say "oh, 12dpo is still too early".  Not likely.  If you are truly 12 or 13dpo and getting a bfn then you are more than 90% out unless you are the exception to the rule.
