AF was scheduled feb 12 and I thought it came the 13. It only lasted a day and half. My fiancé wanted me to take a test last week so I did but barely looked at it cause I'm my head I was like its gonna be negative. Well last night I was getting something other of my bathroom drawer and saw the test and picked it up and it looks like a positive. Then I tested again this morning and it was a negative. Should I go get a blood test? I'm so confused
