Ok long story but I felt pregnant about 2 weeks ago my boobs where hurting I felt funny but anyway I waited a little bit then took a test I thought inseen a very faint positive on a Superdrug test even thou it was 5 days before my period that night I started spotting it was all brown blood but I took a first response the next day and nothing took a clear blue digital nothing so I thought it was over and I wasn't pregnant anymore I took another superdrug test Saturday morning and I got a faint positive ive got a picture but I dont no how to put it up? And Saturday night I bled a bit of red after being on my feet for 7 hours after work and now all my tests are negative again but I havnt bled anymore red I just wanna no if iam pregnant or not? Iam so confused todays the day of my period nothing shown up but no positive surly if I was pregnant it would have shown up on the test should I give up? X
