Period or possible hope of pregnancy?

So TMI but I normally get a very heavy period that has large chunks in it and always have horrible hot flashes and my crotch is sweaty and itchy. Well we have been trying and I've taken a few tests including one the day I started bleeding, all negative. Going off of glow my period is a week early but I always get my period around the 28th so it came early by a few days and has been nothing but medium to light red bleeding with none of the other I listed about. I'm obviously going to retest later this week but what are the chances I may be pregnant? How many others have had this when they were first pregnant? With my daughter I had no bleeding what so ever and with all 3 miscarriages this past year I just had regular implant bleeding where it was blood when I wiped once and then gone
