'The Circle' winner DeLeesa St. Agathe found out she was pregnant during filming

• "The Circle" winner DeLeesa St. Agathe found out she was pregnant while filming the show.
• St. Agathe told Insider that her symptoms hit the day after she took a pregnancy test.
• But she decided not to tell husband Trevor - who she was pretending to be - until after the finale.

Life in "The Circle" is stressful enough. You're forming friendships, contemplating alliances, and weeding out the catfish - all in the hopes of making it to the final and winning $100,000.

But Netflix's hit reality show was even more demanding for season two winner DeLeesa St. Agathe, who found out she was pregnant in the middle of filming.

St. Agathe - who competed on the show pretending to be her husband Trevor - spoke with Insider about the moment she knew she was having baby number two.

"The Circle" winner revealed that she found out she was pregnant about midway through filming the season, but that she "kind of knew in the back of my head" before taking a pregnancy test because she'd started having the same symptoms she had during her first pregnancy.

Even still, St. Agathe tried to keep her head in the game as she survived blocking after blocking in the competition.

"It's one of those things like, if you don't see it, it doesn't exist," she said with a laugh. "I was thinking like, if I don't pay attention to it, I'm not gonna get hit with the early symptoms of pregnancy - the nausea, the tiredness."

The show's producers asked St. Agathe to take a pregnancy test, and it was positive

"I swear to you, the next day it was like bam, nausea, bam. You're 10 times more exhausted than you were these last few days, because now you have a little baby growing inside of you," she said. "And that was pretty difficult for me, I was really tired at times."

"Obviously it's a show, and I came to put on a show. I want to have energy, I want to have fun with it and be really involved. So it was really hard for me to not be so tired," she added.

But the pregnancy gave St. Agathe even more motivation to win the game.

She told Insider finding out she was pregnant gave her "that motivation and push to make sure I do everything I can to try to win that money."

"Even [after the positive pregnancy test], I tried to push it to the back of my head because I needed to focus on the game. I was like, I can't have this take away from my game because now - especially at this point - the game is everything. The game was everything, but now it's everything times two," she added.

St. Agathe didn't tell her husband about the pregnancy until after the finale

She called Trevor to deliver the news, revealing that they were $100,000 richer and expecting a second child in just a matter of minutes.

"I don't even remember his reaction, there was so much going on, he was just so shocked," St. Agathe recalled. "He was like, 'Oh my god, you won, this is crazy!' and then I'm like, 'Yeah, yeah, and I'm pregnant,' and he's just like 'What? You're pregnant? What do you mean!?'"

"At some point all of the emotions kind of hit him, he was tearing up," she added. "It was just crazy!"

St. Agathe already has a lot planned for her future after 'The Circle'

St. Agathe - who is due in about a month - used her prize money for the mortgage on a new home in Atlanta. And she said she's going to keep being a "mompreneur," running both her personal YouTube channel and her family's YouTube channel, which have more than 60,000 subscribers between them.

"People are so invested in what's going on in our lives and our relationship as a couple, as a family, as young parents, and our challenges are on there as well," St. Agathe said. "It's basically our own show on YouTube and that is what I would also love to see in the future - to possibly have our own family show. We have a lot to offer the world!"

In the meantime, St. Agathe is also keeping busy running her clothing store and gift box store. She's also about to release children's books to help inspire "little girls to grow up strong and independent."

"I'm just doing the damn thing, I'm trying to make generational wealth here," she said with a laugh. "I want to make sure my family is good. That's my whole purpose in life, to make sure we are good.
