Can someone explain your highest fertile day only being 33%?

That just seems low. And I know that’s the highest it can get and it’s lower in days leading up to ovulation but what does that 33% mean? Are some of our eggs not good?

We’ve been doing the deed every day during my fertile week so hoping it’s going to be a good result! The 33% is kind of discouraging me though…I think mostly because I don’t understand what it means 😕
