weird cycle... something is off

I got my period on June 9th, it is now the 17th and I am still experiencing some brown spotting and also some wet pink blood mixed with cervical mucous. My period seems longer than usual. Thursday night which was cycle day 7 for me, I had what almost felt like ovulation cramps, it was completely different than period cramps and definitely feels like ovulation cramping. Yesterday morning I found a tiny little bit of what looked like EWCM after wiping.  Which is strange for me being on cycle day 8. Typically I don't ovulate until 2 weeks after my period started. And I've heard it's impossible to ovulate whilst on a period. I just checked my cervical position which I do multiple times through my cycle and it is very high and soft to the touch and feels closed. Which again is strange for cycle day 9 for me and seeing as how I'm still bleeding. I've also noticed for the past 2 weeks I've had intense headaches off and on every single day, sometimes with nausea. And my left nipple will feel like it's on fire sometimes. I'm wondering if something is off with my hormones because my body has been acting strange.. if it wasn't for my period I would Think I'm pregnant! It has to be hormonal! What else could explain this? Has this happened to anyone else ?
