Could I be pregnant? Opinions needed please!

Ashley

I’m due to get my period on Saturday, I’ve been super tired, very emotional, I get sick to my stomach a few times a day, and I’ve been cramping and feeling twitches and bad lower back pains. My CM is white and watery (I get very wet like I didn’t wipe good enough 🤦🏻‍♀️) I have had 3 pregnancies already!! Could I be pregnant or could these just be signs of my period coming??
