How long sonakshi-Krushna are married?

I thought Krushna-Sonakshi are married for 2 years (it was mentioned in dec 13 or 14 episode)....when sonakshi visits Govind's home after Krushna was discharged from the hospital...in todays episode Yashwant sinha mentions Nandini's rape took place 5 years back...well the same day of Krushna's wedding😕

Is there a major change in storyline..😊
What was Nandini's age during the rape and her present age❓

plz comment....am I missing something😕

like u i also don't know 😕
