Yes, that was my first guess as well. Increased income from employment is most strongly associated with major changes, such as promotion to a new position with changed (and usually increased) responsibilities, or leaving one job and starting work somewhere else that pays more.
It seems plausible that these are not the sorts of changes that women are likely to seek out at the same rate when planning to devote a lot of time in the very near future to being a first-time parent. Some may, but all? Seems unlikely. Men seem more likely to continue to pursue such opportunities at a similar rate due to gender differences in child-rearing roles.
