I always got ovary pain when I ovulated! I always expected it to come about two week after my menstrual cycle.
when you ovulate a cyst forms that has the egg inside this cyst can grow slightly and then it pops and lets the egg out, it may be that this is a sign of the cyst popping and the egg being released i think they call it a foliac cyst, if you look it up it is completely normal and nothing to worry about
hope this helps
if its your lower left abdomen thats painful it doesnt need to be ur ovary it could be apendix urine infection, theres a few different things it could be so i think to narrow the list down i would go and see your gp for advice and answers x
