Do I sound pregnant to you?

Ca

So overall summary - I feel like I'm pregnant. I'm currently 3 days late for my period, I was emotional and had cramping all last week, had some white discharge recently, and (this one is hard to explain) I have this like pressure in my uterus. Like it feels like someone is kind of lightly pushing on my uterus. I'm also usually EARLY for my period. And I'm never this late. HOWEVER, I took a pregnancy test first thing this morning and it was negative. What do y'all think? Did I just take a pregnancy test too early? Do I sound like I'm pregnant? Or what?
