Kylie Kelce tearfully revealed that she found out about her past miscarriage on her husband Jason Kelce’s birthday.

In honor of October being Pregnancy & Infant Loss Awareness Month, Kylie got candid about how she found out she had miscarried their first baby in 2018.

“I wanted to share some more details because when I experienced my miscarriage, I felt like a bunch of people came forward to support me and offer words of encouragement or love,” she shared on her “Not Gonna Lie” podcast Thursday.

“So they divulged that they also had experienced losses. It is interesting how sometimes it takes you experiencing a loss for people to open up about their own,” Kylie added.

Kylie, 33, said she and the former Philadelphia Eagles player, 37, started “trying to have a family” and after a few months, had their first positive pregnancy test in August 2018.

The former field hockey athlete detailed being “very guarded about telling people outside of my immediate circle” because she knew of the “rate at which people lose pregnancies.”

“By the time we went to London, I was supposed to be 12 weeks. We made it a point to surprise Jason’s mom [Donna Kelce] and dad [Ed Kelce] when we were there by pretending to take a photo and telling them that we were expecting,” she recalled before beginning to hold back tears.

The couple went on to surprise his family with the baby news while in the UK and later told his brother, Travis Kelce, when they returned to Cleveland.

“All of these interactions were recorded for memory purposes,” she shared.

When the couple left their trip from overseas, Kylie said she went to her 13-week appointment, and the doctors could not find the baby’s heartbeat on the fetal doppler.

“It felt like everything went into slow motion. And they could not find the baby on the Doppler,” she remembered.

“I remember being like, ‘Oh, there isn’t a heartbeat. You didn’t find one because there isn’t one.’ … They estimated that the baby had stopped developing between, I believe it was nine and 10 weeks,” the mom of four shared.

“Essentially, I had had what you would refer to as a missed miscarriage. It means that your body did not realize that the pregnancy was no longer viable.”

Kylie, who had to keep taking breaks to prevent herself from crying, said the day she learned of her miscarriage was Jason’s 31st birthday.

“It was a s–tty day because it was Jason’s birthday. I called my mom and told her that I couldn’t tell Jason because it was his birthday, which seems very silly,” she said.

“It seems very silly because obviously I’m going to tell my husband what happened. And I did. And it was hard for both of us.”

Because of what happened with their first pregnancy, the couple, who tied the knot in April 2018, did not share that they were pregnant with their eldest daughter, Wyatt, now 6, until after 20 weeks.

“For consecutive pregnancies, I waited till I was at least 16 weeks,” Kylie said of her other three kids: Elliotte, 4, Bennett, 2, and Finnley, 6 months.

“I Googled almost every week what the percentage likelihood was that a baby could survive, which sounds really dark. I literally did it for Finn,” she shared.

At the end of her chat, Kylie offered support to other women who may have experienced this heartbreaking loss.

“For people who have experienced loss and who still have gotten to meet some of their tiny humans, I am also sorry because it doesn’t not hurt,” she said.

“It just never leaves you. It is scarring and stays with you in a way that is yours only. Whether you have a loss at six weeks or 13 weeks or whenever, that loss is real. I think it’s important to have people around you [who] understand what you’re going through and who are in on the struggles that you’re having and feeling. And I think it’s really important to have an open dialogue with your doctors.”
