Help! So confused!

I decided to expand on my previous post.

My period is a week late tomorrow. I have been pregnant before. And I have been feeling like I did before. My boobs have been a little sore off and on. And I have been cramping with no bleeding and no spotting. I took a test on Tuesday 7\12 and got a faint line. I took another on Wednesday 7\13 and got another more faint line. I took one today 7\15 and don't see anything. I then took a digital test and it said not pregnant.

Did it not stick? Shouldn't I be bleeding if that's the case..

Or perhaps I ovulated later than I thought and It is still too soon to tell?

Help! I'm going crazy!

It is more obvious in person, but the first two have faint pink lines..
