Cardi B remembers the “really nasty night” she conceived baby No. 3.

The rapper told her Instagram followers in a Live over the weekend that her youngest came to be after she and estranged husband Offset celebrated New Year’s Eve together.

While the 31-year-old initially thought the little one was conceived the following month on Valentine’s Day, the timeline did not match up.

Cardi believed she was six or seven weeks pregnant when she woke up tasting copper — but she was already in her second trimester.

“[My doctor said], ‘You’re, like, 17 weeks pregnant,” the Grammy winner recalled on Saturday. “I was like, ‘No f–king way, I only had sex one time this year.’”

Cardi was shocked to see a “big ass baby” instead of a “little bean” during her ultrasound at the time.

At the time, she and Offset were believed to be broken up after Cardi declared herself “single” in a December 2023 video.

“I want to start 2024 fresh, open,” she said at the time. “I’m curious for a new life, a new beginning. I’m excited.”

When she and her estranged husband, 32, reunited at the end of month, Cardi admitted to “get[ting] d–ked down on New Year’s Eve.”

She confessed, “I needed d–k on New Year’s Eve. I feel like we were vibing. … We had a good time.”

The on-again, off-again couple were subsequently seen together at a Miami dinner and a Knicks game in February — but Cardi neglected to define their relationship while speaking to Rolling Stone.

“It’s not even about love. We’re best friends,” she explained in May. “It’s not even about ‘How do you leave a partner?’ How do you stop talking to your best friend?”

Two months later, she filed for divorce from Offset and requested primary custody of daughter Kulture, 6, and son Wave, 3.

She went public with her pregnancy the next day.

“With every ending comes a new beginning!” the “Bodak Yellow” rapper captioned her August baby bump debut.

The little one arrived on Sept. 7, with Cardi and Offset keeping her name under wraps.

The songwriters have butted heads since her birth, with Offset alleging Cardi cheated on him while pregnant in an Instagram comment last week.

She issued a cryptic response as his claim made headlines by tweeting, “AND DID !!!!!! A hurt Nikka will do the unthinkable.”
