So yesterday I was 9 DPO and I felt a little off so

I thought I would test, I took my first test at 4:15pm on a first response test and it almost instantly was positive, then I was in disbelief so I took another one at 6pm a clear blue and it was definitely positive faster than the original wait time, I was told to take a digital because those almost never give a false positive and so I did and for some reason nothing happen after I peed on it so I got nervous and took another first response one at almost 10pm and was positive instantly again and said I will take a digital in the morning with FMU when I wake up!! I woke up and took it and in about a minute is showed pregnant and today I am 10 DPO, wondering why I am getting such strong test so early?? Here are the test in order from when I took them and these picture are in the time frame of taking them. My doctor has an appointment scheduled for May 22 and it seems so far so maybe someone can help
