The menstrual cycle may be regular in the absence of ovulation, which is called anovulatory menstruation. If you are planning to get pregnant, you should first have a sex hormone test to understand ovarian function and whether estradiol is normal, and then decide whether to give ovulation treatment. The main purpose is to understand the growth and development of the follicles. If the follicles have reached dominance, intramuscular injections of the appropriate medication are needed to make the follicles rupture and expel the eggs as soon as possible, so there are some women who have regular periods but are not ovulating. If there is no family planning, no intervention can be given for the time being.
