Weird?? Help please??

Hi ladies,

Just a quickie. I had a very faint line on a pregnancy test a few days before my period and then I came on my period I did do a test on the day of my period and it was stark negative, so I thought I had a chemical pregnancy, I’ve done a few tests in the last couple of days just to see if it was still negative, BUT surprisingly it comes back as a faint line again!? I have no idea what’s going on and if I am actually pregnant??? Can anyone help please, no nasty comments thanks.
