hpt/IB/cycle length questions????

Okay, so my cycles are irregular. I was very stressed out last month and my period was 3 weeks late! Now, that being said, my period started last month on Aug. 19th. Normal length/flow and all...then on Sept. 7th I woke up to brown discharge which I *thought* was my period coming a week early, but it went away that same day. Now here I am on CD 33 with no period again.

I realize AF still may come and maybe I eally haven't quite missed it yet, with an irregular cycle history. However, I just really thought I was pregnant. I took a dollar store test yesterday and another today and both are negative. I'm bummed.

Has anyone had anything similar occur to them? Anyone have any advice? It would be appreciated.
