Ontop of having a reoccuring or chronic yeast infection, I have noticed for the past few months that my periods have been much much lighter than normal, and the blood isn't the normal red. It's either dark brown, or a dark red mixed with brown during my entire period, which normally lasts 4-5 days. I am on the pill, but is this normal? It's freaking me out. I feel like I'm not having a normal healthy blood flow. Any ideas? Please
