Good Afternoon, I am having some sort of brownish pinkish discharge and flow from the vaginal area. My cycle is usually 28-29 days long. Last month my period was almost 10 days late. LMP was December 24,2013 and November 17, 2013, October 20,2013. I don t know if I am having implantation bleeding or could this be something else. I have heavy flow with lost of cramps and large clots. I am kind of lost here. I don t use birth control
