13 days late!

Destany
Hello, last Tuesday I tested with a First Response gold kit, it came with one line test and one digital. I took the line test in the evening and got a BFN. Then the next morning I took the digital test. At this point I'm 6 days late. It clearly said YES+. 
I took a first response line test this morning and received a BFN. What the heck is going on? I have all of the symptoms, I have an app July 8th. I'm going to request a blood test. 
Digital taken June 23rd in the morning. 
Line test taken last night, but the one this morning is also negative.
