pregnant or not ?!

So I had posted this pic on the glow app for expecting mothers..... someone commented on the pic and said  these are negative because they are so faint ! So then I was like I better get a doc order to get tested and I peed in a cup at 230 pm and it came back negative  my thought is that my hcg levels aren't that high in the afternoon and I obviously drank a lot of water !! So u think I'm prego or what ?! Also I called the doctors office and I said soooo are home pregnancy test pretty legit and she said yes !so if this is right and I'm pregnant gen I'm 4 weeks and two days due around dec 2!!
