Weird symptoms,negative pregnancy test

My cycle is due. I’ve been having brown specks spotting extremely light(only see if when I wipe) over the last 6 days on and off. People have been making strange comments about me looking “chunky” or like I am putting on weight when I am oddly trying to lose weight. I took a pregnancy test it came back negative.

Has any experienced anything like this?

My last pregnancy was 8 years ago, I don’t recall having any symptoms like this. But I also found out early that I was pregnant.
