I am 1 month 11 days late

My last period was 29Sept .My normal period cycle is with in 45 day not more then ever.I took 5 -6 pregnancy tests so far. The last result I got was having a very very faint second line visible at only certain angle. I'm confused as I even have no sign of periods coming. Can anyone suggest whether I'm pregnant or not? Any possibility? 

P.s. - we're trying to conceive.
