Doctor, i had a feeling today of my periods to be starting but i had to make sure to decide whether to offer my prayer(salah) or not accordingly. I am 20 years old unmarried. When i checked by wiping tissue paper over vagina to assure, i saw just brown mucus, i wiped several more times and found same brown mucus. I want to know the cause, please help me to know whether it s normal or abnormal. My periods since 2,3 years compared to my early periods (which used to be heavy and uses to last 6 days), have been lasting not more than 3 days. And i usually suffer from back ache (i know it might have no connection but my mom says you re weak judging my overall period-performance and suffering from back ache)
