Pregnancy possibility?

I know the only time to be 100% sure is to take a pregnancy test but I'm going to the gynecologist on Oct 26, so I will take one then. By then, I should be able to get an accurate result. Anyway, I've been having some symptoms which include bloating, heartburn, DECREASED appetite, craving foods I never crave like tomatoes and olives, gas, headaches, runny nose, congestion, tingling of the (no pain), fatigue and frequent urination. Oh, and lately, I've been very forgetful and I cannot remember simple things like what I ate for the day. I could be over yzing since I just learned that my best friend is expecting. But I'm just not sure. I started using the pill august 26th, the day my period began and after a week on the pill, I discontinued because the pill was making me sick to my stomach. Because I stopped the pill I had three periods in September. One when I began birth control, one when i stopped birth control, and one at the end of the month. So I don't know what's going on with me. Like I said, I do have an appointment next Tuesday, I'm just wondering what are my chances. Does abruptly discontinuing birth control make you more fertile? I did the cervical check and my cervix is no where to be found. Does this mean i'm preggers?
