irregular bleeding advice

Looking for some help/answers/ideas 
My period ended Sunday August 26
This past saturday morning I woke up with severe abdominal pain. To the point where I was sweating, chills, heart pounding and turned gray. No fever I was at 96.3 degrees, did not feel like I needed to puke. Even tried using the bathroom and barely any bowel movement. Almost went to the ER, but  after about 45 mins my body came down from whatever and just felt sore down there. 6 hours later had light pink blood when I wiped. 
Didn't have bleeding until last night. Red and still have it now. Only shows when I wipe. Ovaries hurt, not severe, but definitely can feel them. Lower back hurts 
I've noticed I have had back pain lower for the past could of weeks.
Today I took a pregnancy test, not pregnant.  I also took clear blue ovulation test thinking I'm on cycle day 11 I maybe getting ready to ovulate, but no LH charge. 
Anyone have this? I have never had spotting or inbetween bleeding in the 18 years I have had my period. I was a normal 27 day cycle until I started ttc. My age is 27.
