Hi,
Welcome to ehealthforum.
Hymen is not related to uterus âgrowthâ. The changes that take place in uterus, vagina, cervix and breasts during puberty are caused due to hormonal changes in your body. If you are confused or are not having periods yet, then you should consider visiting a gynecologist for a thorough check to see what could be the underlying problem. Then examination and tests done would also tell if you are having pubertal changes normally or not.
Absence of secondary sexual characters and absence of menstruation could be due to thick and non perforate hymen not allowing for menstrual blood to flow out or there could be other serious issues related to ovaries and uterus which would require further investigations like ultrasound scan, karyotyping test, hormonal level (thyroid hormones, pituitary and hypothalamic hormones that control menstruation etc.) analysis. Discuss your symptoms with your mother or elders in family and go ahead with a visit to gynecologist for further assistance.
Take care.
