Normally, there's no reason why intercourse should cause ovulation pains... However 50% of women experience irregular ovulation pains anyway, so know that you are not alone.
What I would say is if this pain seems particular frequent after or during sex, then it's possible you have either endometriosis or pelvic inflammatory disease (PID).
These medical conditions can be treated or managed, but are often really tricky to diagnose - so I would suggest getting checked out early on to rule them out.
