Cardi B wasn’t expecting another pregnancy. Last January, she underwent surgery to get butt injections and fibrosis removed from her body which called for two blood tests.

Both came back negative for pregnancy, Cardi explained while on Instagram Live. After the operation, when she was busy promoting her single “Enough” and one morning she woke up with a tell-tale sign.

“I woke up one morning and my mouth tasted like copper,” she said. “And I was like, ‘Oh my gosh, this only happens to me when I’m pregnant. So, I immediately knew that I was pregnant.”

Cardi concluded she was around six or seven weeks pregnant. However, her doctor soon clarified that was not the case. “She was like, ‘You’re not seven weeks pregnant or six weeks pregnant. You’re like 17 weeks pregnant,’ explains Cardi.
