Temp rise but no positive opks

Je

This is what my chart looks like so far this month. I've been using clearblue opks (the ones with the pink caps) and still haven't gotten any LH surges on them, but my temp has definitely risen! Any chance I ovulated and it didn't pick it up? Or still a chance for me to ovulate? When I did this with my last 2 pregnancies I would get LH surges CD 13-14 with peaks on CD 15. I used a different OPK then. Thanks for your help!
