Faint lines and now negative?

Chelsea
Ok so I'm 3 days past AF and no sign of it coming I've had 2 faint positives on pregnancy tests I've done a few days ago and they was all morning urine and I've just done another test not testing with morning urine and it looks negative to me :/ has this happened to anyone before I'm very confused as I haven't had any bleeding since the faint positives. All these tests were done with first response
