London, Nov 18 (ANI): A Brit woman was stunned to find out she was six months pregnant with her fourth child - because she had been sterilised 13 years back.

Debbie Amos, 43, had become pregnant with her first son, Glen, who is now 19, after a course of fertility treatment and after his birth she and her husband Melvyn, 57, decided not to try for any more.

However, she gave birth to two more and following that she asked doctors to give her an operation to ensure she would not become pregnant again.

Doctors had warned the couple that sterilisation might only be 99 percent effective, but both took it for granted that it would work out.

When Debbie came to know she was pregnant with her fourth child, she was a little apprehensive because of her age, but felt relief after Connor, was born healthy at Colchester General Hospital weighing 8lb 8ozs.

“We were very relieved he is fit and healthy. I didn’t have any tests as I didn’t know I was pregnant until so late on and there were obviously added risks because of my age,” the Telegraph quoted her as saying.

“My doctor said maybe the tube had grown back, but we don’t know.

“My husband was thinking about retiring from his job as a transport manager when he was 60 but that won’t be happening now,” she said.

But she stated she had no regrets about the unexpected arrival.

“Obviously, I would not be without him for anything now, but it has been a massive shock. Maybe he was just meant to be here,” she added. (ANI)
