I’m only like 6dpo! Does this look invalid?!? As the line is darker at one end then the other. 🤷🏼‍♀️

I had a chemical last month and I tested until the tests showed completely negative. I’m only aprx 6dpo but my breasts were killing me all day today and I decided to test. I probably shouldn’t have with it being so early 🤦🏼‍♀️ and I just got this result. The line isn’t as thick or dark on the bottom as it is the top! Do you think it’s invalid?! I did find some other tests online that were positive that looked similar.
