I give up!

I just want it to be positive. Going from getting 2 faint positives one week to a blood test that is negative one day and test that are now negative is so depressing. Like I only spotted for 2 day after my missed period and it wasn't implantation. I'm starting to give up. Idk why I'm even counting the weeks anymore it's pointless. Its only been 3 weeks. 😔😔😔😔😔😔😔
