Still No Period!! Negative Pt!! Please help me!!?

Hey well today I took a $1.00 pt. I peed right before I took the test. So then I had to pee again so I decided to go ahead and take it and see what it said. I have took a pt early this month and it came back a very very faint negative. Which I heard was a positive. Idk, im 25 days late and it has been either 56 or 57 days since my last period which was May 6th. I was spotting to day it was very bright red and had a tiny clot too. This can't be my period because I have done that earlier this month also and it lasted maybe 1 day and a 1/2. Its not a full blown bleeding just when I wipe and nothing in the toliet after i pee. I still believe that Im pregnant. I'm having heartburn as we speak. I have cramps like period like, lower back pain, i sleep a lot, i could wake up really late and still want to go back to sleep like 1 hr later. I'm really thirsty, and I just want to know if i'm really pregnant because I never miss a period. Im usually like 32-33 days regular. I'm just super curious and if i don't start soon or something then im going to the ER. Please help, can I still be pregnant? I'm getting really disapointed when the test say NEGATIVE. I just want a POSITIVE. Have this ever happened to anyone? Please Help. Please no rude remarks im just worried.. Thank You!!! Have a great night!!<3
