When Lucy Hellein, from Fort Mitchell, Alabama, was fitted with an Intrauterine Device (IUD) in August, she was pretty confident that pregnancy wasn't something she'd have to consider at least for a few years.
But, to her utter shock, about four months later, she discovered that she was pregnant - and not just 'a little pregnant' but already 18 weeks along!
This wasn't the first time Hellein had an IUD, in fact she'd had two Mirena devices before this one was implanted. The tiny, T-shaped device is inserted into a woman's uterus to prevent pregnancy.
This particular type of IUD releases the hormone levonorgestrel that thickens the mucus on the cervix, preventing sperm from entering and eggs from leaving a woman's ovaries.
"I found out I was pregnant in December and I’ll admit I was scared because of the Mirena," Hellein told the Mirror.
Hellein's device, the Mirena, has about a 0.2% failure rate, as long as it is inserted correctly...
