My gut feeling is P had full proof plans to be surrogate... So she also saved her eggs.. and right at last moment switched her eggs with Sai's... Making it a Virakhi baby.
Posted this theory few days ago but the overwhelming consensus is ki 'didi ke paas itna dimaag nahi hai' 🤣
This was in continuation to that ... Because V and now Sai too has gone soft on P... Illegal Surrogacy bhul gaye hai...They need a much bigger betrayal to realise the depths to which P can go 😡
