I'm pregnant.. Right?

Mi
So I usually have a 38 day cycle.. It's day 47. I am great at convincing my body I'm pregnant every month LOL 
but it's never been THIS late. 
I took three tests two days apart each. First: negative, but 2nd & 3rd: faint line. (2 different test but still looking for that straight down line. Top test from today but different brand and I can see it on both easily with the naked eye) 
I'm really slow to believe the faint lines but I know from what I learned that's enough to know! 
I've never been pregnant and I really want to know so I can tell my hubby :) just needed a second opinion at this point before I go to a doctor. Thanks :)
