We often forget how vulnerable women can be when they are birthing their children. Even in this day and age, when medical science has made so much progress, there are a lot of things that can go wrong.

Unfortunately for this family, a rare complication took place and caused them to lose their loved one… Keep reading to know more.

It was Kelli Tyler’s fifth time being pregnant. The young mother from Oklahoma was excited about being a mother for the fifth time. She was actively posting updates about her pregnancy.

But shortly after giving birth for the fifth time, Kelli tragically passed away from a rare complication due to childbirth.

Last week, Tyler changed her profile picture on Facebook as she prepared to give birth again. A day after that, she passed away.

“The amniotic fluid got into Kelli’s bloodstream [and] she was losing blood more than she could take in,” Julie Roach, Tyler’s mother, explained. “I think the last words my granddaughter said — she said — were, ‘I’m about to faint.’”

An amniotic fluid embolism is a “dangerous and life-threatening complication,” according to the Cleveland Clinic. It can happen when someone delivers a baby or shortly after they give birth.

The reason it can be deadly is because it is “very difficult to diagnose because the symptoms can be similar to other serious complications during childbirth.”
