So confused

Shae • After TTC for a year or over, I’m finally pregnant with baby #1!

So yesterday I took a pregnancy test & it had a SUPER faint line. Today I took another and it was a little darker but still faint. I went to the hospital and had a blood test done & the blood test came back negative. I’m not sure if a qualitative or quantitive test was done with the blood he didn’t specify. Has this ever happened to anyone else?
