Help me PLEASE!

Lindsey • 🌈🎀 💙| expecting number 3!
These are just a few of the tests I've taken over the last few weeks. It seems about 70% have these faint lines and 30% are negative. How long did you pregnant/previously pregnant women have faint lines that didn't get darker as fast as they should have?
I am trying so hard not to get my hopes up, and have an appointment on 9/8 for blood. 
What are your thoughts ladies? AF was due 8/8
