The Duke and Duchess of Sussex are now expected to become parents before April is out.
Meghan Markle told the press earlier this year she was due at the end of April or the beginning of May. However, it now seems the odds of her giving birth in May are low, because her husband Harry and his sister-in-law Kate arrived at Westminster Abbey in London on Thursday.
The pair's presence are a likely signal the Duchess could be opting for a home-birth, rather than one in hospital.
Harry and Meghan already announced that, unlike both the Duke and Duchess of Cambridge and Prince Charles and Diana before them, the couple will not give birth at the prestigious Lindo Wing at London's St. Mary's Hospital.
They also confirmed recently that, unlike William and Kate, they will wait several days before showing their newborn to the world when it is born.
