Help me understand my BBT please.

I normally ovulate around CD17. I have yet to get a peak on my OPKs. Lots of highs, but no peaks. The last few days I’ve experienced nausea, dizziness, Left and Right Pelvic Pain, sore breast and nipples. Yesterday I woke up with a sinus infection.

My cycles average 31-34 days.

Any advise would be great!
