Bfp with hardly any symptoms?

Has any one gotten a bfp when they dont have really any symptoms of pregnancy or af?

Past few days ive been getting light headed and been extremely tired like I could sleep 24hrs and still go right back to sleep and ive also been very emotional for absolutely no reason like I want to just sit and cry over NOTHING and that is not me im not a cryer at all. And that is the only symptoms im having and usually with af so close my boobs are usually killing me and there not even a little sore but my nipples are a sensitive.i took a test this morning and it was neg but af isnt due till sat. Is it possible im pregnant?
