Why do some get early and some get late BFPs?

[tag74]

I feel like I should know the answer to this question, and where I can understand early BFPs, how do some get late BFPs? Like 14, 15, 16 etc? Is it miscalculation of O?

Just would love some opinions.

I agree everyone is different. You cant compare. Our bodies make hcg at different rates. For some people their hcg rises faster in early pregnancy than others.

I will think it depends in the individual metabolism. Like some people will eat a lot and not gain weight and others (like me) will gain weight by smelling food!! And like some will process the anesthesia at the dentist right away, while others take a while.

That is just my opinion.
