Here's How NASCAR Driver Kyle Busch & Wife Samantha Felt When They Lost Their Last Girl Embryo

In a recent interview, NASCAR driver Kyle Busch's wife Samantha shared about the loss of their second child, a daughter, whom she called their "last girl embryo."

Kyle and Samantha had spent much of this year looking for a willing surrogate to carry their second child. The couple finally found her this past September.

Unfortunately, in November, when their surrogate took a pregnancy test, it came up negative. Samantha shared the sad moment on her Instagram page. She told PEOPLE that it was their "last girl embryo."

"Our surrogate walked outside, Kyle turned the camera off and we just broke down," Samantha explained to the publication. "You put so much faith and hope in every round."

It has been a longstanding struggle for Kyle and Samantha to have their baby number two. They have a successful in vitro fertilization treatment that resulted in the birth of their son Brexton in 2015.

However, after welcoming their first child, the couple, who tied the knot in December 2010, has endured heartbreak after heartbreak in their struggle to have a second child.

Samantha and Kyle are spreading the word about their Bundle of Joy Fund.

Samantha miscarried the daughter they had conceived via IVF in November 2018. However, according to the couple, their fight to have another child was not at its end.

Meanwhile, Samantha is always at the track if her husband is racing. But due to the ongoing COVID-19 pandemic, she has been forced to watch most of his races from home with their son.

Samantha, Kyle, and Brexton are on the road for 13 weeks out of the year. The doting wife and mother told Fox News that it is super busy all the time.

Samantha and Kyle, who is often nicknamed "Shrub," have been married for a decade. The couple does not let their traditional lifestyle stop them from spending quality time together as a family.

Samantha and Kyle are spreading the word about their Bundle of Joy Fund, an organization they launched that has helped bring 25 children into the world to date.

The organization helps couples with the costs associated with in vitro fertilization treatments. Samantha explained to PEOPLE that many couples need an average total of over $50,000 in IVF treatment.
