Period or pregnant?

Stephanie • 24 • Wife • Expecting my 🌈

My period is due tomorrow.. i’ve been having cramping, sore breasts/nipples and creamy CM for a week now. I had very light pink spotting once at 8dpo. Took a test yesterday and it was negative. Today i have a large amount of watery CM and i’m always running to the bathroom thinking i started AF but i’m just wet.. i also have cramps. What are the chances of this being AF or pregnancy??
