First time charting- plz help! :)

Hi ladies!  I have never charted my BBT before, and started this month with my first round of Clomid (50mg) on CD5-9. I have PCOS and have no period at all when not on Provera/BC. Have not been trying actively until March, but have not avoided pregnancy for 3+years, but nothing has happened. 
Can someone more knowledgeable please take a look at this chart and see if maybe ovulation has occurred??  I took an OPK strip every single day from CD10- CD25 and only got a faint line on one day.  As of today (CD28), my HCG test is a negative. 
Any insight would be appreciated. 
Thanks so much!!
