ovulation confusion through I know kit

Preeti

My cycle is of 29 days and as per this my ovulation start date is around 12th but when I checked by using I know kit it is showing two lines c and t from 7th. As my periods ended on 5th of this month so I thought I should start check from 7th but I got confused as it kit shows two lines on 7th then I again checked next day it again shows two lines then I again checked on 9th result same two lines

So please suggest should me start make relationship now???
