Late... pregnant?

Im am ttc child #2. It took almost 11yrs for our first child. Well i am 6 days late on my other app and 5 days late on this app. I have taken 2 first response test, one of which was digital, both negative. Last pregnancy i was 5 days late on my other app when i tested and the line barely showed. I'm so frustrated. Dont know what to do......
