As per your symptoms, it appears as though your uterine lining has been shed in toto and this is perhaps the reason for the disappearance of the pain. The cause for such a shedding is related to the endometrium, be it hormonal
, due to infection or endometriosis
. Since you are already on treatment for ovarian cysts, such a thing could happen. Please report the matter to your gynecologist at your next visit. Hope you find this information helpful. Take care.
