Testing 9 dpo to early???

Good morning Glow TTC Moms, I decided to test again this morning to get a more accurate answer…because I tested yesterday and seen faint lines on a Walmart blue dye test which I heard blue dye give off false positive so I took a First Response after and I thought I seen the faintest line. I posted pic of those test yesterday. This morning, I took a easy @ home test and a CVS brand blue dye and it was negative. I’m so confuse…I’m having symptoms: tenderness breast, lower back pain, cramping, and nausea. So I’m not sure what’s going on. My AF start Aug 26…. Is there still hope for me…this my first cycle after my nexplanon removal. I was hoping to get pregnant on the first try.
