I need advice!!

Ashlee • Baby mccausland due July 13th!
So I took one of the clear blue tests I saw a faint line, so I went in same day to planned parenthood because I wanted a quick re assuring test. It came out negative and they save its a high sensitive test and is completly accurate. So the next day I took another clear blue test which was sunday cause I'm was 4 days late still and I got the one on the left with a little darker line. Now iv been told by many friends that dollar tree test actually work,so I went and bought some and took one this morning because I am now five days late and it came out negative then at 3 PM today I took a first response test which is the pink one and it came out positive I have no idea what to think or do. So mixed up!
