Very confused and frustrated

Destany
Found out I was pregnant June 23rd, negative test June 30th. Started spotting with clots from the 1st of July to the 7th. 
I was told that since it was such an early loss that my period would NOT be affected, yet I'm 23 days late.
So if this really is just my cycle being super messed up then why do I feel pregnant? Why am I nauseous when I wake up and randomly throughout the day? Why am I urinating more? Why have I been bloated for so many weeks? Why have my breasts been killing me for almost two weeks now? Every freaking test I take is negative. I just want an answer either way! Pregnant awesome, period then fine. At least I'll know what's going on. I feel like I'm in cycle purgatory :(
