Help..

Kiley • Pregnant with rainbow baby! ❤️👶 due date April 20th!
I ovulated on 6/22 and I got a faint but definitely there positive on 7/4. Later that night, I got a not pregnant on a clear blue digital. The next morning I got another faint positive with fmu, but this morning another not pregnant with a clear blue digital. 
Could it be because I am still too early? Af isn't expected until 7/17 because I have long cycles. Going to test again Friday. 😓 I need advice and positive vibes.
