In fact, bookies are now convinced Meghan won't go in to labour until next month.
"We were surprised as everyone else that Harry decided to attend a public event as we assumed the baby was imminent," a spokesperson for William Hill told The Mirror.
"We are now odds on that baby will not arrive until May."
Meanwhile, a palace source told the publication: "If anything was to happen in terms of a labour, he (Prince Harry) would be able to leave at a moment's notice but you may infer from his attendance that perhaps the due date is not necessarily today."
