hello, Pain and discomfort during mid cycle, typically two weeks before the menstrual period suggests that ovulation takes place. It is common and usually harmless. The pain is felt on the right or left side, depending on which ovary is releasing an egg. Pain usually persist for 2-3 days. As your ultrasound report is good enough, then you have nothing to worry. You can take some anti spasmodic medication to get relief from this. Avoid stress, take healthy diet with more vegetables, control body wt and need proper sleep. Be well & take care.
