"We’re so beyond thrilled!" the 38-year-old actress gushed to ET's Leanne Aguilera over the phone, adding that the couple discovered the baby’s sex by cutting into a gender reveal cake. "I was convinced I was having a boy because I've been having such an easy pregnancy -- no morning sickness, no weird acne, nothing weird. Several of my friends who were having boys were having the same kind of pregnancy. When we cut into the cake, I was completely shocked. My husband was like, 'I knew the whole time that it was a girl!'"
The Hawaiian native, who plays Colleen on the CBS sitcom, told ET she was gearing up to attend the Sundance Film Festival when she started to suspect she was expecting.
"I just felt like I was pregnant," Cabral shared. "Jason was on a business trip, so I waited until he got back and was like, 'I think I'm pregnant. I'm taking a pregnancy test.' He was like, 'Whoa, whoa, whoa -- so soon? That’s crazy!’ I took three in a row and they were all positive. We both bawled."
"He's such a good dad already," the 38-year-old revealed. "He's so attentive, nurturing and sweet and now that I'm starting to show, he just can't get over how my body is changing. He's so in awe, so happy and we talk to her all day long."
Due in late September, Cabral has managed to avoid morning sickness, but confessed she’s been craving "everything carb and everything cheese."
The actress' friends, including her Life in Pieces co-star Zoe Lister-Jones, are currently planning her July baby shower and she will then return to work around early August -- ready to hide her baby bump from the camera.
"From what I understand from my writers, they don’t want Matt and Colleen to have kids just yet. I think we have enough kids on the show!" she said with a laugh.
With less than five months to go until her little girl is due, Cabral is loving being pregnant, admitting that she has found the experience surprisingly empowering.
"For so many years, I was scared and had trepidations," she confessed. "[But] from the beginning, I've loved it. I feel special, mature, feminine and [like I’m] embracing my feminine power. I know that sounds earthy and weird and that's not really my vibe, but this is beyond me. This is literally a miracle and I feel so lucky."
