Chart Help - Ovulation

This is my chart so far and I'm confused. I'm on CD 29 and I stopped doing OPKs after I got my first peak reading (that's what the instructions said to do) on CD 27. 
Once I got the peak, I thought I would've ovulated within a day or two, but today my temp still hasn't spiked. I had some EWCM this morning, but we also BD'ed last night and used PreSeed so I'm not sure if it's accurate. And my cervical position is confusing me even more. Lol. 
Any thoughts would be appreciated!
