No no nooooo
Karan died 8 months ago when she was 1 month pregnant - she kept the news from him only for a couple of days
Now, 8 months after his death she is 9 months pregnant which means nearly full term (40 weeks).
2 problems with this timeline - normally its rare to get a pregnancy confirmation at 1 month, usually u will not even suspect until u miss your period & doc will then ask to wait for another couple of weeks just to be sure. Secondly it is too late to hold god-bharai at 9 months, usually held aftr 7 months - but we can excuse the delay due to all the troubles in their life!
