Lindsay Arnold is thinking about expanding her family with husband Sam Cusick again. "Me to my husband: 'Maybe we should start trying to get pregnant this month,'" Arnold, 31, wrote over a TikTok video on Sunday, August 3. "My IUD still in my body: ..." Arnold set the video to Taylor Swift's song "I Forgot That You Existed" and lip-synched to the lyrics, "I forgot that you existed / And I thought that it would kill me, but it didn't." "Maybe next year? #momsoftiktok #momhumor #pregnancy #babynumber3," she wrote in the caption.
