question: I m 17 and this is my second month talking the birth control Generness Fe. The first month my period came out to be normal. Two weeks later, I had my period again; this time is was lighter. A week later, I have gotten my period again which I am currently on. Today is my 9th day having it; it is very light (such as my second period in the first month), and I have no pains or anything. So my question is, why is my period longer than 7 days?
