Am I tripping?!

I posted almost a week ago after taking a pregnancy test due to the fact that my boobs have been sore and I been cramping. The test was negative (it was 12 days before my period). I took a test today now that it's 5 days before my period just to be sure since my breast are still hurting. It was negative the whole time that I stayed in the bathroom for about 10-15 minutes. I came back hours later to take a shower so I took the test out of the trash to see if it was still the same but it came out looking like this! Also, I kept the test I took almost about a week ago and that one still has only one line. Could I really be pregnant? Or maybe it was just sitting with the urine in it for too long? Lol
