Smart campaign inside multiple nurture stream

Hi all,

I am trying to implement the below mentioned flow:

Send Email1
if respondent didn't click on link in email 1 in last 7 days send email 2 
If respondent click on link in email 1 in last 7 days then send Email 3
if respondent click on link in email 2 in last 7 days then send email 3.

Suppose i have sent Email1 on sunday morning and person A clicked on link on monday then will get email 3 on next coming monday and if person B clicked on link in email 1 on tuesday then he will receive email 3 on next tuesday.

I have tried to implement this using smart campaign and three stream in nurture program. But its not working properly. So please guide me

Thanks in advance.
