Allen, 28, who has 23-month-old Ethel and 10-month-old Marnie with husband Sam Cooper, lost her first baby when she was six months pregnant after she became ill with a viral infection, reported Contactmusic.
"I couldn't get my head round how people could be so horrible. But I learned pretty quickly that I was very vulnerable, and this (the internet) wasn't the place to spend my time. I still think about it 25 times a day," Allen said.
The singer is grateful to have the support of her husband during the tragic period.
"There are women who have to deal with this on their own, so even though it was tragic, I knew where I was in the world and the people who were important to me and what mattered, and what didn't," she added.
