Sanya Richards-Ross’ rainbow baby is on the way!

The “Real Housewives of Atlanta” star is pregnant with a child she conceived one month after a “traumatic” miscarriage.

“I didn’t think it’d happen so quick again,” the Bravolebrity, 38, told People Thursday.

She joked that her husband, Aaron Ross, “prides himself” on “never miss[ing].”

The reality star, who is currently four months along, went on to reveal her Christmas Day due date.

“I just couldn’t be happier,” Richards-Ross gushed to the outlet. “I’m so ready to meet this little one.”

Notably, the retired athlete’s pregnancy will not be covered on Season 15 of “RHOA.”

Although she showed Ross, 40, a positive test during the mid-season trailer, which aired earlier this month, Richards-Ross suffered a “really bad” miscarriage two months after filming the scene.

“I had to go to the hospital,” she recalled. “I had to have a blood transfusion. It was very, very, very scary.”

Can’t get enough ‘Real Housewives?’

Richards-Ross called the tragedy “really difficult,” adding, “You already opened your heart to becoming a mom, so it was awful. Even just talking about it.”

Although the Olympian was “nervous” and not “ready to go through something like that again — that physical, mental and emotional pain” — her doctor encouraged her to keep trying.

Now that Richards-Ross is expecting, she has “never felt more beautiful.”

The track and field star gushed, “It’s been a hard journey getting here, but I am so glad for the obstacles [be]cause they made me that much stronger.”

As for her 5-year-old son, Aaron II, the little one is “over the moon” as he asked for a sibling “every day” before Richards-Ross conceived.

“His reaction was so special,” she recalled. “He said, ‘God does answer prayers!’ And I could just see that joy and renewed faith in him, which made this all that much more powerful for me, in a way.”

“The Real Housewives of Atlanta” airs Sundays at 8 p.m. ET on Bravo.
