Weird period

Lauren

Okay so I’ve been tracking my period cycle consistently on here and the past couple of months it hasn’t been wrong about the day that I’m supposed to start. All of the duffle this month my period decides to show up 4 days early. And it was light spotting light cramping which I am also usually the complete opposite of that. Could this be something else? Can you get a light period if you’re possibly pregnant. My body is so confusing
