Actress Erica Cerra is pregnant with her first child.

The Canadian star, who is best known for her role on sci-fi series Eureka, is due to give birth in late May and she admits her journey to becoming a mother has been virtually worry-free so far.

She tells People.com, “I am so thrilled I am going to be a mother. I fall in love a little more each time my baby moves.

“So far pregnancy has been a breeze. Sciatica (pain in the lower back and leg) can be difficult, otherwise I have been very fortunate. Ultrasounds are probably my favourite - being able to see my little one. It’s all an amazing experience.”

Cerra, 32, wed her high school sweetheart Raffaele Fiore in November, 2010.
