How long after the initial whitening period will menstruation occur?

Patient's question:

No

Doctor's answer:

Irregular menstruation during puberty is generally caused by incomplete development of ovarian function. Teenage girls are in the stage of development and often exhibit menstrual irregularities. Some may not have their second period for 2 months or even half a year, so there is no need to worry. Menstruation will gradually become more regular in the future.
