Actually Mauli was on surgical contraceptive when she & Kunal were in love, so that kind of turns down the chances of her being pregnant. When she removed the contraceptive, Kunal was already after Nandini & Kunal rejected her advances. When Nandini was in splits about Kunal, Mauli told Nandini on how she desires to get pregnant & has gotten her contraceptive removed. (After 2-3 days of this news, Kunal proposed Nandini). Mauli revealed her desire to get pregnant to Kunal only on Pooja where she wore Red Saree & at that time he was already in relationship with Nandini. So, Mauli getting pregnant isn't possible if we go by what they showed in episodes.So, going by the show's timeline-1 week- when affair was on full swing.1-2 weeks since the revelation.It would be completely different story, if Kunal-Mauli slept some time & that wasn't shown in the episode. But that would mean Kunal slept with Mauli, while he was with Nandini too, which would be ultimate assassination of his character.
