I get clue -First bachuva revelation..??

Today episode main frustration scene...today vivan beats suraj.😡😡but imli Devi willingly agreed that..when vivan inform suraj is a father of imli's child..she was silent at the nick of time ..(I didn't get onething why did imli get shock.??.when vivan tell suraj is father of her child..her expression is really weird.😕. ) she is really shocked .particularly I don't understand one thing why did she was silent.. something wrong related to first bachuva revelation.😕she is really shocked..her expression has exposed something weird..she must have told lie everyone that she was a pregentant of suraj's child before ..so she gets shocked few time 😡 as well as afterthat she got conscious after few time..then.i think she is paying back if she told ie in her life...(big twist hidden in the first bacuva revelation)
