The Duke and Duchess of Cambridge are prepared to arrange their calendars accordingly. Should Kate, 34, become pregnant, the source says she and William, 34, will curtail their royal tours in 2017.
After all, Kate suffered from hyperemesis gravidarum (a.k.a. acute morning sickness) with the first two pregnancies.
The source says the royals would also be cautious because of the spreading Zika virus, which causes birth defects in unborn babies. Until she's pregnant, it’s business as usual: They are due in Canada for an official visit from September 24 through October 1.
