AF due Dec 6th, feeling bloated.. Still pregnant?

Jessica • Mother of two boys ages 8 and 4. Both were unplanned and this is my first time actually trying! With my SO for 10 years.
Is it common to feel bloated while beginning of pregnancy? My AF  is due dec 6 but I'm feeling bloated and cramping on my left side. I have an appetite increase these past couple days though. Could I still have a chance of being pregnant?
