Trying not to get down :(

According to glow AF isn't due until 10/26 but my periods are irregular in length after stopping birth control so she can show her ugly face as early as the 21st or as late as the 29th.  I couldn't help but test this morning because the TWW is killing me but I got a BFN ?. I know it could still be too early but I really hope this is my month and was hoping to see an early BFP after seeing so many get them at 7DPO!
