The star's character Mercedes Fisher is currently expecting her first child on the soap, but the actress insisted that she isn't feeling broody in real life with her French boyfriend Sylvain Longchambon.
"I do want kids one day, I absolutely love them, but playing a pregnant character doesn't make me broody," she told Reveal. "It just makes me sweaty having that bump on!
"It's very weird. I've got to wear this big ball around my tummy, and it's so hot and rubbery that it sticks to your skin.
"People catch me rubbing my tummy, but I'm not broody at all - it's just because it's so uncomfortable."
Metcalfe also recalled in the interview how she started her career as a child actor until opportunities dwindled. She returned to acting after working at a local gym.
"It was a nine to five job selling memberships and I just realised it wasn't doing anything for me. So I got an agent and decided to get back into acting," she said. "It was very difficult starting at 21 because I'd been out of the business for a while.
"Eventually I was put forward for Hollyoaks, but I had to go back eight times before they offered me the role. I'm proud I dug myself out of somewhere I wasn't happy."
Metcalfe recently revealed that she only now feels completely comfortable with her body.
