In the letter it was clearly written that u are lieng to vr family that u are pregnant but truth is you are not pregnant . Maybe she lost her baby but in yesterday's ep vr has confirmed that her baby is safe , maybe vr has got to know that she is lying but to know truth he told it is fine . Maybe she abort baby due to se reason. Itne dino se pet mein bacha tha or ab achanak se pet se gayab ho gayi lgta hai bacha Mr India hai . I don't think she fakes her pregnancy but after looking today's emotions of her for her professor , she said u know how much I love u and never love anyone maybe , riddhima kya hai kisise bhi pyar krti hai pehle kabir vansh or ab piche se professor doctor bhi aya .Hope for the best think positive. Lgta hai sad ending hogi or usmein bhi dotu ki Bali chadegi , maybe she is doing this to trap bm or maybe it is vr trying to dig riddhima s past and she also said when vansh will know about her past he will break never love her nor trust her .
