I started bleeding earlier than my expected period, and I felt like something was different about me. I felt like I was pregnant. I took a test (first 2 pics positive tests) . Then I began to bleed and cramp for about 4 days (bright red blood ive never seen before. Took another test. Absolutely nothing.... could this be a chemical? Should I go see a doctor?
