What Causes Nausea Along With Abdominal Pain And Light Pink And Brown Vaginal Discharge?

I ve been nauseous for weeks now, at random times throughout the day. It s been very hard to eat because after everything I eat I get a stomach ache. I ve had a lot of discharge and sometimes it s brown, greenish, or light pink. My pee is orangish yellow and cloudy. I m constipated a lot, I can t use the bathroom normally. It occasionally hurts to use the bathroom. I have sharp pains on my lower right side when I put pressure on it. When there is no pressure on it, it feels like there is something pushing an organ against my ribs. I m still a virgin so I know I m not pregnant.
