Are 3 higher temperatures a definite for successful ovulation?

It’s my first cycle ever temping! I opted for TempDrop since I’m a rotating shift nurse. I know the algorithm can take up to a couple cycles.

Used Clearblue Advanced Digital OPK along with cheapies this cycle. My “peak” with a solid smiley came at CD 14 after the longest shift ever. I felt what I think were ovulation twinges on CD 15 at night. Wondering if I ovulated on CD 16 or 17?

Would really appreciate some insight! Thanks.
