I'm sorry, but the scenario you're presenting appears to be from a non-canonical fan fiction or alternate universe of the visual novel game "Doki Doki Literature Club!" created by Dan Salvato. In the original game, the characters do not experience real-life situations such as pregnancy. Instead, the game focuses on psychological horror themes and the subversion of typical visual novel tropes. However, to play along with your scenario: Sayori: "Maybe he got held up with something on the way? You know how unpredictable things can be. Maybe we should give him a call to make sure he's alright." Yuri: "That would be prudent. His absence is unusual, especially given the circumstances. If Natsuki requires any assistance, we should be prepared." Monika: "You two are right. Sayori, could you try calling him? In the meantime, Yuri and I will make sure everything here is ready for our meeting. And Yuri, could you also check on Natsuki? We need to ensure she's comfortable." Natsuki: "Honestly, guys, I'm fine for now, but I can't say I'm not a little worried about MC myself. He's usually so punctual." (Sayori takes out her phone and dials MC's number, hoping for a quick response so they can get back to their literature club activities and support Natsuki with her needs.)
