However, if no bleeding occurs after progesterone withdrawal, then the patient's amenorrhea is likely to be due to either a) low serum estradiol (i.e. premature ovarian failure), b) hypothalamic-pituitary axis dysfunction (such as low GNRH or low FSH that lead to low estrogen level ), c) a nonreactive endometrium, or d) a problem with the ...
The lack of menstruation usually begins shortly after beginning the medication and can take up to a year to resume after stopping its use. [41] Hormonal contraceptives that contain only progestogen, like the oral contraceptive Micronor, and especially higher-dose formulations, such as the injectable Depo-Provera, commonly induce this side effect.

During the reproductive years, bleeding that is excessively heavy (menorrhagia or heavy menstrual bleeding), occurs between monthly menstrual periods (intermenstrual bleeding), occurs more frequently than every 21 days (abnormal uterine bleeding), occurs too infrequently (oligomenorrhea), or occurs after vaginal intercourse (postcoital bleeding ...
