Hi. From 2nd may, i am having a weird dark brown vaginal discharge in clots. It is not continuous. Only found when i wash my vagina. My period is expected around 14th may, and i have not engaged in any sexual activity in recent few weeks. Today, in the morning, after urinating while washing my vagina, i found one big clot of darkest brown blood almost black in color and then creamy white mucus with tinge of red blood streak. Please help. What is this all about?
