The actress announced her pregnancy last month but explained that her schedule fits around her due date.
"We are shooting six [more episodes]," Poehler told Fancast. "We will be premiering in the fall and then sliding the schedule a little bit for a hiatus. You won't even notice."
Poehler added that she has found it easy to conceal her pregnancy while filming.
"Well, we have just been kind of lucky in the past couple of episodes," she said. "Frankly, it's a combination of good camera work and a good wardrobe department."
Meanwhile, executive producer Greg Daniels joked: "As we get closer [to her due date], Aziz [Ansari] will be constantly standing in front of her."
Ansari added: "Or I will have a pillow under my shirt and also have a baby bump."
