?Chemical pregnancy

Hi everyone. So I had my first faint positive pregnancy test on Thursday. They have remained faint (photos attached) I have done 2 x clear blue weeks indicators on Saturday and today and they both say not pregnant. Only getting faint lines on other tests. Yesterday was supposed to be my period so I assume by now it should definitely say pregnant on a digital. I just have a feeling that it’s not happening this month but still heartbroken to have had that initial thinking it was our month 😔 Has this been the same for anyone else? Thanks x
