Hi All, I am here to discuss something regarding my last periods. It was very erratic. Even my menstrual cycles was very normal. This time at 1st day yellowish fluid came out ,at 2nd day very low quantity of blood and at 3rd day it was dark red like black. I am very nervous about this. Please let me know about this . I am unmarried and not sexually active. I am 20 +. looking forward for your replies.
