Pregnant?? TMI

I had light bleeding for 2-3 days on the 5th which was about a week before my predicted period (i also never spot) I took a pregnancy test today (one of the cheap walmart ones) came back negative. AF is two days late and still no period. I am having some symptoms such as very vivid dreams, headaches, back ache (sometimes it feels like it need to be popped even if i popped it), hunger i think, and i don’t know if i’m nauseated i haven’t thrown up yet. opinions please! i’m discouraged!!
