I don’t know what to think anymore.

I have no idea what’s wrong with me. For the past month, maybe a little less than that, I’ve felt like complete shit. I have to pee ALL THE TIME, or I at least feel like I do. I’m always nauseous, or I always have a stomach ache. No appetite. Horrible cramps. Headaches. I’m always tired. I was paranoid about being pregnant for a while, but my chances of being pregnant are slim. I use the combo pill at the same time every day and my boyfriend pulls out each time. I doubt I’m pregnant. I recently got tested for a uti but the doctor said there wasn’t enough of an infection for him to give me antibiotics. There was something there, but he said it was too small to treat. What the hell is wrong with me? Does anyone have any ideas? I’m so sick of feeling like shit. Should I go get tested again for a uti? I really didn’t like this doctor. He made me feel like an idiot for seeking help. I just want to feel better.
