Confused? :/

Me n my fiance had a miscarriage with twins back on Sept 1st and 3rd, 2014. Since then we have been trying n I feel myself tricking myself into believing I'm having pregnancy symptoms every month before AF. This month I gave up being so hard on myself n let Glow help out. AF should be here tomorrow but for the past couple days I've had low bak pain like crazy, I feel super bloated n like there's a balloon in my abdomin, I'm super hungry then I start to eat n get full so fast, lingering small headache, dizzy n light headed when I move quickly, insomnia like crazy, but super tired the rest of the day, n of course nauseous, hightened smell n frequently goin to the bathroom. Also my normally very independent youngest child has suddenly attached to my hip n will not leave my side... I tested yesterday dollar store brand got BFN...I'm waiting till missed period to test again but wanted to see if those are good signs or am I crazy?!
