During the taping of season 15 of The Real Housewives of Atlanta, Sanya Richards-Ross revealed that she was pregnant with her second child, but two months later, she suffered a miscarriage. Now, she is shedding light on that experience.

The track and field Olympian revealed to PEOPLE that she miscarried two months after learning she was pregnant. News of her pregnancy was also teased in the mid-season trailer of the reality show.

She told the outlet, “It was very traumatic. I was in New York and had a really bad miscarriage. I had to go to the hospital. I had to have a blood transfusion. It was very, very, very scary."

"You already opened your heart to becoming a mom, so it was awful," she added. "Even just talking about it... it really was a difficult time."

During this devastating moment, she reflected on her family's past and future with her husband, former NFL star Aaron Ross and their 5-year-old son, Aaron Jermaine.

"I had been an athlete, competing across the world while representing Team USA. Then, after retiring from sports and having a son, all these life changes hit Ross and I simultaneously. It was like a tornado hit our relationship for that 14 years prior to having our son was like a honeymoon at the time. And It was really overwhelming."

She explained, “I didn't realize until then how much I really wanted to become a mom again and how much of a blessing it is to be a mom.”

And a blessing it has become! About a month after she miscarried, Richards-Ross got pregnant again. "At my age, it's considered a geriatric pregnancy, so I was nervous that the window has started to close. And after the miscarriage, I wasn't ready to go through something like that again — that physical, mental, and emotional pain. But my doctor assure me that everything looks good, and sure enough, it worked.", she said.

Richards-Ross admitted that she did not believe she would conceive so soon after a miscarriage. She said, “I didn't think it'd happen so quick again. But my husband, he prides himself. He's like, 'I never miss. Whenever you're ready, I'm ready.' "

She is currently four months pregnant and due on December 25. She told the outlet, "It's going to be the best Christmas gift ever.
