period due on the 11th of January..

Hey everyone, hope everyone had a great New Year's eve with loved ones. I'm due for AF on the 11th this month, hopefully she will not show. However, I am feeling cramps and have gas since yesterday. Never had this before 7days before my AF. It usually comes a few days before I'm supposed to start. Has anyone experience this before? And could it be a sign that we might be pregnant? I did everything this month! I used soft cups and pre seed also did the mucinex I heard about. Please let me know your thoughts?
