Testing a Theory.. please read!

So I took this test hella early because I was having weird symptoms and talked to my psychiatrist (I’m on meds). She insisted I take a test even tho I got my period in November 22nd and I’m like okay whatever. So I take it and I’m like wtf. I’m 4DPO currently.

This picture is clearly negative.

BUT. The urine hit that antibody strip HARD and a line stayed until it dried. It was almost like it tried to grab on to some HCG and just wasn’t enough. It’s never done this to me, always barely tell that it’s even passing the antibody strip.

Anyone have this happen when testing too early but end up pregnant getting a BFP later DPO?
