Unusual cycle w/ other symptoms..?

Period was 5 days late in May and only lasted about 2.5 days..it was very unusually light most of the time..than about 2 weeks after that period started I started spotting a brown discharge for about 2 days...than following that I had a clear jelly clump like dicharge for about 2 days....other on and off symptoms are headaches, dizziness, cramps,constipation, minor nausea here and there...I can drink 2 redbulls an go to sleep right away..my period is due to start again in about 5 days. I'm 28 and this has NEVER happened..I've been having a period since I was 11yrs old and the only time I had period problems when I was on the depo shot...I'm not on any bc right now. I've had an awful lot of stress in my life too and still always had a normal period...if not heavier when I was stressed....any insight? I've read that it could be ovulation bleeding but I've never in my life spotted during ovulation.
