Hi, I Have Pain In My Lower Abdomen. When I

Hi, I have pain in my lower abdomen. When I touch the area it's very tender, almost feeling like a bruise. I can't feel any lumps. I am also experiencing unusual vaginal discharge, an increased need to urinate, discomfort during sex and a general feeling of fullness in my lower abdomen. Could the symptoms all be connected? And what is a likely cause please?
