If LH started rising mid afternoon on cycle day 16, when will I have ovulated?

LH peaks 24-48 hours before you ovulate, so you need to know when it peaked, not when it started rising. If it peaked on CD16 then ovulation was probably CD17 (but could be CD18), but some women have a very quick rise to their LH peak and others have a slower increase so it depends on the individual.

Would you say cycle day 17 based on my test? @CluelessInLondon thank you!
