Taylor and Cartwright, who got married in June 2019, in front of 240 friends and family at the Kentucky Castle in Versailles, Kentucky, recently told PEOPLE exclusively that their first child is due in April 2021.

"We had been trying for around five months and we just can't wait to grow our family. I had the ovulation sticks and all the apps... we were ready to go!" she said. "I woke up super early to go to the restroom and just had a feeling I should take a test and it was positive!! I cried, I laughed, we were just so happy!! Then I took three more tests and cried some more."

Cartwright added, "I can't wait to start shopping and getting the nursery ready. I am just so overjoyed and every day I fall more in love. Boy or girl, we are just so ecstatic!!"

The couple previously told PEOPLE that they had not decided on a name for a boy. "We have a name for a girl but not sure about a boy's name yet! I think I will continue to look at the baby name list until the day they are born!" Cartwright said.
