Unknown dpo. PCP said it could be “false positives”

I saw my pcp today to ask questions about my chronic conditions and her response to this picture was it could be “false positives”. She doesn’t want me to get my hope high. I have my first OB appointment scheduled for July 1. I’ve had 2 chemicals before and this is the most progression I’ve seen compared to my previous experiences. Feeling confused . How do the line progressions look so far? I tested positive on June 15th so I did take a lot of tests that day to confirm.
