Since June I have not seen my menses and all pregnancy test is negative even sca

Thanks for your question. Generally speaking, the five links leading to amenorrhea are abnormal development of hypothalamus, pituitary, ovary, uterus and lower genital tract. For example, mental stimulation, drug-induced amenorrhea, premature ovarian failure, uterine adhesions, endocrine abnormalities and so on.I would suggest you to have a checkup done in your local hospital to find out the cause. If it is caused by uterine adhesions, you can take our natural medicine Fuyan Pill to get a cure. Hope this answer helps and best regards
