"A lot of stuff went on and I just didn't enjoy it," Cheryl told thesun.co.uk.
However, Cheryl is enjoying motherhood.
"(Being a parent) changes your life completely but in the most amazing way. But I've had the best six months of my life. Really. I hated being pregnant. A lot of stuff went on and I just didn't enjoy it," Cherl said.
"I didn't stop for 14 years -- literally on the roller coaster. And then when I got pregnant I thought, ‘Right, I just don't need this stress.' So I relaxed.
"It's been actually over a year but it's been perfect for me because it's reset the mind-frame. And I feel actually better coming back. I feel more relaxed, I just feel I've sat into my own skin. I feel so good," she added.
