I've had septate uterus, hysteroscopy, laparoscopy. while exercising i felt a twinge, during clean and jerk move w heavier weight. can i hurtmy uterus?

Maybe: If the hysteroscopy repaired the septum inside the uterus, then that specific item is probably O.K. However, lifting and "jerking" heavy weights for females with or without a support belt can cause a pulled round ligament which serve as a pair of "gudewires" to hold the uterus in place.

Probably not, but: Probably not, but depending on how extensive the septoplasty was (and by what method, ) you should ask your surgeon what restrictions he or she prefers for you.
