I feel like Sulo will do some arrangements to ensure that Pallavi's results come out positive. Cause I think she'll bribe the doctor. Sulo has been dying to prove Pallavi pregnant for so long. Even when she was dizzy and not feeling well, Sulo heavily implied it.
And when Pallavi was sick, the doctor's name was zoomed in and shown. So highly possible that Sulo takes the opportunity to bribe the doctor and ruins Pallavi's relationship with her Baba.
