Denise surprised many when she announced late last month that she was pregnant.
While congratulations flooded in for the Wedding Bashers star, she opened up about what a miracle it was after being told by doctors that she had 1% chance of falling pregnant.
"My doctor said I had endometriosis. An urgent treatment was needed, which meant falling pregnant was indefinitely placed on the back burner. Only 1% possibility to conceive, even after treatment for some time.
"I was shocked, and felt less of a woman. I was not eager to fall pregnant, but it has always been important to me to have a family one day.
"I thought, 'Wow!' I didn't realise that falling pregnant could be quite a difficult and physically painful experience. It became clear that breaking away from work and focusing on my family - the 'here and now' that was incredibly fruitful and exciting - needed my entire focus."
