Hello Doctor, I just turned 45. I just started my monthly for the month and I notice a horrible order that I never had before. Nomally the blood is light in color and smells very fresh, but this time it is dark in color, thick and smell horrible. I have no itching, burning when I use the bathroom or any discomfort whatsoever. What could the problem be. I don t think I can see a doctor during my monthy because am sure my doctor will want to examine me.
