Hi there,
Ovulation is the commonest cause of lower abdominal
pain. Few other causes of lower abdominal
pain are PIDs,ovarian cysts, fibroids, STIs, RTIs etc.You need to be evaluated for above mentioned conditions. Consult your gynecologist. A clinical examination and tests like pelvic scan, hormonal assay may be helpful. Keep me posted with more queries. Hope it helps.
Best luck and regards!
