Still waiting

I got tested for a UTI. Negative. I told the person who took me back for the test that I was TTC (she herself was VERY pregnant). She said she had issues with UTIs when she was trying. So when she called with my negative results she said .... 'This could be a good thing!' *in a really excited voice* Really that's not what a 2wwer at 4 dpo needs to hear!! So yesterday I was CONVINCED I was pregnant. Today not so much. And the downward spiral begins.
