Prince Harry arrived in the UK on Sunday, ahead of Prince Philip's funeral, without Meghan Markle.
The Duchess of Sussex has been advised by her physician not to travel for Saturday's service as she's carrying the couple's second child. Little Archie will turn two years old on 6 May.
A source tells E! News, Meghan "wishes" she could have flown to the UK though. "She would have put all the family tension aside to be there with Harry."
The insider adds, however, following Meghan's miscarriage last year: "Harry wants to make sure Meghan and the baby are healthy and not involved in stressful situations."
A second source tells People the queen "understands why" Meghan is unable to attend, and the couple have been in constant contact with Harry's grandmother following Philip's death.
As for Prince Harry, sources say there is hope he will repair his relationship with the royal family, and William in particular, during this time. The brothers are expected to stand "shoulder to shoulder" as they walk behind Prince Philip's coffin at the funeral service.
