Fans first met Doug and Marsadie, who goes by the nickname "Mars," on Season 1 of TLC's hit show Rattled, and after this week's episode, they're now wondering if she's pregnant — for the second time. The couple — who already have a daughter, Sophia, 2, — opened up about their relationship, since many are skeptical that their foundation is strong enough to endure another birth.

"Doug and I are not married, but it's something that I would like to see happen down the line," Mars, 29, said, to which Doug replied, "We'll see." Yikes. The 42-year-old revealed that he went through a "bitter, acrimonious divorce, and it made me a little more stoic and a little more cautious." The two met online three years ago when Doug messaged her and said, "Drinks on me for life?" Clever! Since then, however, it's been an uphill battle. Mars admitted, "Since having a baby and moving in together, things have gotten more volatile." Doug added, "We fight a lot."

On Tuesday night's episode, Mars revealed that she thought she may be pregnant because she was "a week late," which she claimed was the first time that's happened since Sophia was born. She told a friend, "The idea of having another kid right now is just too much." She added, "I think that reliving the being up all night and trying to care for a newborn while we're trying to raise Sophia would be disastrous. Our relationship is too fragile to handle that." Unfortunately, we have to wait until next week to find out — ugh! Towards the end of the episode, Mars handed over her pregnancy test to Doug, who responded, "I think I'm going to have a heart attack."

Tune in next week to find out the results — we bet she's not pregnant! What do you think?

Rattled airs Tuesdays at 10 p.m. EST after OutDaughtered!
