Could i be pregnant?

i dont rly keep track of my period, but im 100% positive i should have gotten it by now.general guess im about 2 weeks late. when i had i was pretty sure it was after ovulating and i thought there was no way i could be pregnant. ive had symptoms of pregnancy; some that are similar to what i experience before my period and some are not. more frequent hunger [ i did have what i thought was a craving for spiral ham..?], cramping [lighter, and slightly different than my normal pms cramps], weird abdominal phenomena, bloating, tender [but not heavy] , i feel tired and in a daze, heartburn[is that even a symptom?? lol] and a single light twinging [but definately noticable]headache. im pretty young, and i was looking for some information. it's not easy for me to get to a family planning center or to get a home pregnancy test, but i should have one by next monday at the latest. could anybody tell me if they had any of these symptoms or if they think i could be pregnant?
