Pregnancy test very faint line help!

So before my supposed period I bled so lightly for like 3 days but so very light like tiny drops of blood I thought it was my period but no I always have a heavy period. So today I took a test and it showed a very very faint line and I took another 2 tests different brands and 2 out of 3 is negative. I am about to have a blood test on Monday.

my husband didn’t cum in me he never does but he said twice he did just a tiny tiny bit. It wasn’t even a full load and now I am late and pregnancy test shows this am i pregnant?
