Bbt chart help!

Jane
I'm 6dpo temp and opk confirmed ovulation (I do have pcos so it's possible I geared up but didn't ovulate). I'm a bit dizzy and overall just not feeling well today... But bbt don't seem to confirm my thoughts. I could really use some of your thoughts on my chart... We have been ttc for 4yrs and next cycle will try IUI and on to IVF if no success,
