Let's assume this baby is the outcome of a love relationship. Then the boy cheated or died . The sisters plan to get a abortion or they decide to put the baby for adoption . So they manage to hide it from indrani for 3-4 months. But they need help from someone so they approach mama. Megha and shika were studying some where else, they came to the haveli recently . So she goes back there probably lives with mama and completes her pregnancy period there. She does not come home siting about studies. Since mama was with her, indrani does not think it is necessary to check on her. Only thing that Shikha also needs to be aware of the whole issue.
That is the only possible explanation
