I could used a couple of opinion please,?

MLP was 11/26/09 . I saw my egg ewww mucus on the 12/09/2009.. then on the 15th when checking my cervix I saw light red blood only when I wipe then later gone. then as of the 19th till today I have had a couple things going on like a lot of cervical mucus , also if I drink a coke in the morning I'm throwing it up. and I use to drinking my cokes. but p week can't... besides that I get cold then I'm hot also been having a running nose. . so does it sound like I'm coming down with a cold or is it pregnancy ??????????????
