Hi and welcome to HCM.
It sounds like you have pain around ovulation and this is most commonly caused by ovarian follicular cysts or hormonal
imbalance. You should do pelvic ultrasounds and blood hormonal levels to evaluate this. Also endometriosis
may be considered,but probably this is something benign-
RBC is usually found raised in women because of menstruation
,but sometimes it can be sign of urinary infection or kidney
stones. Wish you good health.
