I last had my period March 28th which was all normal, I was meant to come on again on the May 1st but AF didn't show so I tested on the 4th and it was negative so I didn't think anything of it. Then yesterday (7th) I got a tiny bit of spotting just when I went to the loo so I thought that wasAF coming but since then I've had nothing else which is very unusual for me. Am i right to think I'm not pregnant since I've already done a test, or could it be wrong?thanks.
