Perhaps your pain during the time of ovulation is indicative of ovulation from the right side. The cause of the present pain could be due either to some pelvic or urinary infection or due to tubal cramps which sometime occur during a menstrual period. Please consult a gynecologist for a proper evaluation; you may also need a urinalysis
, sonogram and blood counts. A pelvic antibiotic along with an anti-spasmodic usually relieves the condition. Please maintain genital hygiene and eat healthy food. Hope this helps.
