Ovulation cramp (mittelschmerz)... How closely does it align to ovulation?

Hi friends! This is for those of you who expertly track your fertility with temperature or test kits (or have in the past) and ALSO experience ovulation cramping...

How closely does this pain align with ovulation?

I am currently trying to AVOID pregnancy, and I often get the pain on day 12 or 13 of my 29 day cycle. The general assumption is that I am ovulating on day 14 or 15, but I’m curious how accurate this is.

In your experience, is the pain an indicator of current ovulation or upcoming ovulation and what makes you think this? Google searches are inconclusive, so I thought I’d reach out to women who know their bodies well!
