Could I be pregnant?

Kelsey
I have no idea when I ovulated. But my period is supposed to be 8 days away. I'm very irregular due to my pcos. I am experiencing a large amount of cervical mucus, extreme hunger, mood swings, a pinching feeling in my lower abdomen and a few other things. I totally get that I could just be getting ready to start my period. But I just don't feel like this is my period.
