I am an 18 year old female. I have not had my period in three or so months (I am not sexually active). I also have shortness of breath and I am bruising very easily. Easily, as in someone gently grabed my arm and there was a bruise of their finger prints on my arm. I have also developled a rash on my stomach and under my arms. I am very concered and do not know really what to do. Any suggestions?
