Not sure what to think...

I have an odd cycle, but I've always gotten AF between cycle days 28 or 30...I'm either almost 6 days late or almost 4 days late. I have pressure and cramping like I have a cyst on my ovary, and lots of symptoms. Couldn't stop crying over a stupid mistake at work. My boyfriend and I had sex last night and we realized I was bleeding, bright red blood (usually darker for AF). Initially thought it was my period, but now I have a tiny bit of brown discharge. Took EPT Saturday night and got a BFN. I really don't know what to think...
