Confused as hell

So. My boobs have been sore for a couple weeks. A few weeks ago I had a bit of cramping that was on my left side of my uterus. My boobs we noticed are like a cup size bigger almost.

I NEVER get symptoms whatsoever with my periods. Never have.

My period is almost a full month late.

BUT I took a digital test and it says I’m not pregnant.

So I’m like lost. I’m trying to wait it out as far as the dr goes cuz I’m seeing her the 14th
