A South Dakota mother’s worst nightmare came true during the harrowing birth of her twin daughters – which began with her ‘water bag’ coming out intact.

Jessica Vandrovec showed no signs of complications during her 2010 pregnancy. But within a matter of minutes, her world came crashing down.

‘I went into the bathroom and just started screaming for [my husband] because my water bag came out of me intact,’ Jessica recalled to KELO.

‘And so I just held onto it, and I made sure there was no baby in there. And we called for the ambulance, and they took me away.’

The water bag, formally known as the amniotic sac, is the ‘protective bubble’ that a fetus grows in, according to the Cleveland Clinic.

The sac contains fluid that helps cushion the fetus and regulate its body temperature. It also holds the umbilical cord and placenta.

An en caul birth means a baby is born still inside the liquid-filled, thin casing. Under normal circumstances, a doctor will use tools to cut it open after birth.

It is not clear whether Jessica had an en caul birth, but the emergency forced Jessica’s twin daughters, Breley and Kailey, to be delivered at just 24 weeks, incredibly underweight.

Tragically, only one of the twin baby girls would survive. The Vandrovecs are now hoping to raise awareness of their troubling story.

As Jessica said, her daughters were not inside the sac when it unexpectedly came out of her.

It is unclear how much Breley weighed, but Kailey was just one pound, six ounces, KELO previously reported.

Jessica and Terry spent the next 133 days in the NICU as the newborns battled for their lives.

‘At first, it all just blended together. I mean, it’s a world that doesn’t stop. Ever. There’s no day, there’s no night,’ Jessica said.

This frantic span of dread and uncertainty left Terry with a mild form of narcolepsy. On top of it all, the couple had another child at home.

Breley tragically passed away shortly into her time in the NICU. Jessica said she saved her sister’s life.

‘Leaving the NICU with one kid felt really wrong. Like I knew I was leaving something behind,’ Jessica said.

Once the grieving parents returned home with the sickly baby, tending to her constantly to make sure she remained alive – all while mourning her sister.

‘There was no time to feel sad,’ Jessica said. ‘There were times I would hold Breley’s blanket and just cry because it still smelled like her.’

In the years that followed, Kailey continued to struggle with her health. When she was two years old, she put into a medically-induced coma and was on life support, her mother said.

Kailey was then given a gastrostomy tube, or a G-tube, which is a feeding tube inserted through the abdomen into the stomach.

She had the feeding tube until she was about eight, but once it was removed, yet another dilemma arose.

The hole the tube went through started leaking stomach acid, and Kailey needed another surgery.

Horrifically, the surgery did not go as planned, and doctors said her stomach and liver had fused.

Her stomach had a two and a half inch hole in it, explaining the leak, KESO reported.

Now a freshman in high school, Kailey’s health has drastically improved. She has even joined her high school’s volleyball team.

But she told KESO that peers can be cruel at times, as they do not understand what she has gone through to get to this point in her life.

‘People are like mean to me sometimes,’ she said. ‘They don’t know the story behind it all. They’ll say stuff about my voice, knowing that I can’t change it.’

Jessica has decided to write a book about her family’s taxing story to help others who may be faced with earth-shattering challenges of their own.

‘I don’t want to say that there’s a reason Breley died. Because I would love to have her here, but it changed us,’ Jessica said.

‘And that two-day-old baby showed us what fighting really looks like and what love really is.
