symptoms?

August 22 was the last 'first day of my period'
September 6 was my normal ovulation time (during that time I had a lot of gassy, crampy feelings, stabbing pains left and right, and in the evenings I noticed light blood on my panty liner)
Once I saw a dark ovulation line but no bright positive test on September 7; otherwise, always negative.
From Friday the 12th to Saturday the 13th of September, I couldn't sleep because of really intense stabbing pains.
After that, I always had gassy bowels, low and open BMs. Last week, I had a lot of watery discharge.
Since yesterday, I've had a very bad bitter taste in my mouth, suddenly bursting headaches, and I feel very nauseous.
This morning I had some brown discharge and when wiping, a light pink smear. I'm feeling a bit nauseous again, and I've also been really hungry for yellow foods. My period is normally due on September 19.
Who can relate to these symptoms?
