I see no contradiction here. :) My weeks are possibly in a similar range as yours, now that I'm no longer avoiding it, I haven't used the site in months. This lines up with my understanding that it's endemic, and at a high level of prevalence in the population (in my area of the US). This also lines up with my understanding that the majority carrying it are asymptomatic, and that among the symptomatic, only the unvaxed or immunocompromised get sick enough for it to be the primary cause of hospitalization. Hence, significant danger only exists for the unvaxed or immunocompromised. The website is helping you think about the risk through approximating the probability of getting SARS-CoV-2. For me, I've accepted that P ~= 1. What it's not telling you is the probability that when you contract SARS-CoV-2, you'll regret it, or even know that it happened. The OP is in a completely different situation though. Vaccines aren't approved for a newborn (tho, there's promising indications that pregnant mothers who are vaccinated pass some benefits to the child!), and putting that aside, for OP, contracting even asymptomatic COVID could mean missing the birth, which I'm guessing has a cost approaching -infinity.
