could i be preggers...or just coincidence?

Ok my last normal period was August 27-30...I was supposed to sart Sept 23 but didnt until the 26th...when af came it was heavy and dark, full of blood clots but it only lasted 2 days. Since then I have been tired, increasingly hungry, but queasy, headaches are very frequent(usually every afternoon),mood swings, tender breasts, and lower abdominal cramping, as well as constipation. I know this is tmi but i had a mc earlier this year and while i know it is too soon to check i am anxious to find out asap to prevent myself from going thru the same ordeal again. When i had my last vaginal sonogram for this miscarriage, everything was healthy with the exception of scartissue from 2 previous c-sections. Other then feeling pregnant...am i seeing too much into this? Please help advice greatly appreciated.
