In our thoughts.

Bachelor Nation first met Sarah Herron on Season 17 of “The Bachelor,” and she returned to our screens for Seasons 1 and 3 of “Bachelor in Paradise.”

In September, after many highs and lows of her IVF journey, Sarah revealed that she and her fiancé Dylan Brown were expecting a baby boy.

Then earlier this year, Sarah took to Instagram to share the tragic news that their baby boy Oliver passed away shortly after he was born prematurely at 24 weeks.

Now, in honor of National Infertility Awareness Week, Sarah just penned an emotional essay for Women’s Health where she opened up about losing her son.

Sarah shared how along their IVF journey, they were ecstatic that Oliver’s embryo came back with what’s known as a “Day 5 AA” grading, aka, he was a high-quality embryo.

The Bachelor Nation star said, “As I progressed through my pregnancy, we passed all the usual tests with flying colors; DNA carrier screenings, the nuchal translucency test, and bi-weekly ultrasounds — we cleared all of them with unwavering confidence.”

She went on, saying, “But against all odds, despite the genetic testing, the surgeries, and mounds of medications to ensure a successful pregnancy, at 22 weeks, we discovered Oliver’s condition. Something that couldn’t be screened for, that we couldn’t have seen coming. After all we’d been through, it felt as if our son was struck by lightning.”

Sarah shared that Oliver was diagnosed with an unexpected health complication that was incompatible with life outside the womb.

She shared that two weeks after the diagnosis, Sarah gave birth to Oliver at 24 weeks after 20 hours of labor.

Sarah said, “He came out beautiful — far too beautiful. He had my nose and his father’s long limbs. Shortly after being held skin to skin by both of us, Oliver quietly passed. He came into this life feeling love, protection, and warmth and left it knowing only the best of life’s offerings.”

The Bachelor Nation star shared a special quote that she thought of in this extremely difficult moment.

She said, “It reminded me of a scene from Season 4 of Yellowstone, after the death of John Dutton’s grandson, where he says to the boy’s mother, ‘That boy lived a perfect life, Monica. We’re the only ones who know it was brief. All he knew was you and that you loved him.’ Oliver’s time here was brief, but we’re the only ones who know that. He only knew his mother’s love.”

Sarah said that the past few months have been filled with immense grief, loneliness, and pain. She detailed her changing postpartum body, despite not bringing her son home with her, adding, “As a mother, you show up for your children — regardless of their time on earth.”

And now, a few months later, Sarah reflected back on how she and Dylan have been processing this unimaginable loss.

She said, “The stars aligned to create our son with a deep, meaningful purpose bigger than we’ll ever understand. His body was small, but his legacy will always be larger than life to us. While our hearts are shattered beyond comprehension, and we would much rather have our son here with us, we are comforted knowing that our son’s soul only ever knew love and will not suffer in a body that wasn’t built for this life. He wasn’t struck by lightning... he was magic.”
