I took three dye pregnancy tests on 10/24 & 10/25 all three were a very faint positive. Ive had fatigue, cravings, headache, increased appetite and urination.

Today im 4 days late and all of a sudden i started bleeding when I went to the bathroom. Not alot but more than spotting and it was orangeish brown. Then im having moderate cramping so I decided to take another test to be sure, this time i took a digital one. It said not pregnant.

Which test was wrong? And if i am pregnant why am I bleeding? Im so confused and hurting. Please help!
