I’m so confused 😩 help?

I started spotting three days before AF was due, barely anything the first day (one wipe after BD right before bed), then very light throughout the next day, then back to barely anything the day before AF due (one wipe). Today AF was due and absolutely nothing. I’ve had no pms symptoms, I usually pms and my cycles are regular. Took a pregnancy test this afternoon and negative, although the urine was diluted I feel like that had to be my period? But why so short and early and barely anything? This actually happened two months in a row right before I got pregnant with my first. I’d love to believe I’m pregnant but my hopes aren’t high. Any chance it’s indication my body is trying to get pregnant again?
