6 days late, one positive, rest are negative. Pregnant or not?

Steph
Currently TTC, 6 days late and have all the pregnancy symptoms but no sign of AF. I had a positive pregnancy test during my fertile window and the rest have been negative. I don't know what to think about it. Re taking a first response in the morning and have an appt next Thursday at doctors. What does everyone think? Really need some advice. We want our little rainbow so bad. 
P.s. 
I have really bad self control with taking pregnancy tests!😂
pregnant?
