The 36-year-old actress and comedian discussed her romance with Fischer on Monday's episode of the You Up? with Nikki Glaser podcast after marrying the chef this month after a few months of dating.
"Part of the thing that's good about us getting married so quickly is that we're so in love," she said. "Every girl I know, if they get proposed to they're like, 'Oh now? Now that I can't have kids!'"
Schumer said it "feels [expletive] good" to have wed Fischer and be able to call him her husband.
"I'm a wife as hell. But it's still like, a novelty," the star said. "Somebody went to sit next to [Chris] and he's like, 'My wife is sitting here,' and then I got back and he was excited to tell me that he said that."
"I just have been really overusing it to a degree that's insane. Like, when it's completely uncalled for," she added.
Schumer and Fischer tied the knot Feb. 13 in a secret ceremony in Malibu, Calif. The actress shared a new slideshow of photos Feb. 17 from the reception, which included pictures with her sister, Kim Caramele.
"Thanks for always always being with me to have a celebration Chardonnay when something big happens thanks for loving me and Chris," she wrote.
