The consultant and her fiancé Wise announced her pregnancy exclusively to PEOPLE in March, while well into her second trimester.

“I was very excited to find out I was pregnant. I wasn’t sure if it was going to be possible since I was diagnosed with endometriosis when I was younger,” said Role, 33.

The former reality star took “six pregnancy tests and then two more a few days after” to confirm the happy news, which was “the most amazing dream come true,” she told PEOPLE.

“Just being able to have this experience and create something so amazing with the man I love is all I ever wanted,” said Role about her growing family. “We are both so overjoyed and cannot wait to see what the future holds.”
