The actress, who plays Leah Patterson-Baker in the Australian soap, announced her pregnancy last month and it was later revealed that it would form part of Leah's storyline.
"It does throw things out of whack, that's for sure - undoing and redoing story retrospectively is always a challenge, but having said that, Ada's pregnancy is such lovely news that none of us mind the extra work at all," Bowes told Yahoo.
"We're just so happy for her and Chris and wish them both well. Anything is possible in Summer Bay, but I can guarantee it'll be an interesting journey for Leah."
She added: "We were faced with the challenge on All Saints of dealing with Georgie Parker's pregnancy - that was a tricky one given that Georgie's character was a nun!"
Nicodemou's character Leah suffered a miscarriage last year after falling pregnant to friend Miles (Josh Quong Tart).
