Please help— is it looking like ovulation can still be confirmed?

I was so confident with my timing this month! Strong positive opk on CD 15 in the morning and afternoon. Negative the next day (I usually have a very short surge) and very negative today. All the other signs were there but my temp is rising very slow for me. Usually I have a big surge in temp 1 dpo. If my temps continue to rise could there be a chance I still ovulated in CD 16 or at all? I know I need to wait for more temps but I’m going crazy and want to see if this can be normal.
