I need help 😩 okay , so about a week before my period I started getting dark brown / black discharge . sometimes stringy , other times coming out as tissue looking . but I had it the whole week before my period , and had it when I should've had my period . some days heavy , some light . depends . I don't know what it might be ?? anyone have ideas ?   I had this problem a few months ago with dark discharge. but it did not last as long , and my OBGYN said it was okay , but to come again if it reoccurred . I have an appt Thursday . but it would be nice to hear opinions
