You have a chance!!! Take a test and see!!
What day of your cycle are you on? I am normally aswell on a very tight 28 days cycle and am heading into day 31. I am hanging in there until cd34. I usually get obvious signs a few days out from AF and although I am having similar symptoms to you, I am preparing for a possible late cycle. If I were you I would take a test and if it is negative try again in a few days if you have not gotten AF yet. Good Luck, I will cross my fingers for you.
