What do you think am I or am I not!!!!!?????

ok, so according to this site, I am about 12 DPO and am due for AF in two days. I have had tightness (very mild cramping) for about the last week and a half or so. I have been peeing a lot in the last few days, like a whole lot, dizzy the last two days, and heartburn too. I have not noticed headaches as I usually get these if I have been drinking soda and havent had one, and I dont pay attention to back pain or a few other signs as I work for an airline lifing bags in and out of planes etc. I first thought the peeing was due to drinking a lot of water, but I have been extremely thirsty lately, have not really noticed cravings, but I know Im NOT craving my usual things, like I usually eat very healthy, but I have just had not interest whats so oever for veggies, or healthy items. also, Iusually loves pasta and chocolate, but dont even give them a second look.... I noticed some tenderness but thought that was due to working outside in the cold that we have been experiencing here ( I live in a warm climate).
Also, I just came off BC about a month ago so I dont know if this is my body playing tricks on me, but I have come off of it before and never had this feeling. I usually only cramp the day before and day of really hard. What do you all think. I took a early respoons HPT six days before AF, but it was a BFN. I have two days left and really want to test again, but also dont want dissapointment... Any advice would be great!
