hello, welcome to this platform Drying of vagina and scanty vaginal discharge are symptoms of hormonal changes in the body. The hormone responsible for vaginal discharge is estrogen. so you are going through some changes in your body leading to decreased sex hormone production. Drying of vagina is a problem for women in perimenopause and menopause, hormonal imbalance can also occur in women who have premature ovarian failure, polycystic ovarian syndrome (PCOS), anorexia, or pituitary and hypothalamus issues; and in women who have recently experienced childbirth, are breastfeeding, have imbalanced diets, have gone through cancer therapy, or smoke cigarettes. One very important cause of vaginal dryness that often goes unrecognized is stress. which can interfere with the normal female sexual response cycle. i would recommend a natural approach to your symptom of vaginal dryness: Stay hydrated. Choose gentle hygeine products. Eat a balanced diet. Increase soy isoflavones in your diet. Take a medical-grade nutritional supplement. Try a quality lubricant. Look into vitamin E suppositories. lastly think of....Considering phytotherapy and other hormone therapies. for your postcoital bleeding it may be due to dry vagina since your recent pap smear report is normal.. if the bleeding is heavy kindly visit your doctor soon. and if the bleeding is of little amount it will subside in a day or two, till then maintain good local hygiene , main abstinence. hoping my advice will be helpful for you. take care.
