I’m a 22 year old female Very overweight I’m making

Patient: I’m a 22 year old female. Very overweight. I’m making an appointment with my gyno, but I’d like some feedback in the meantime. I had an appointment with a new physician on Friday. He gave me a physical and said everything was fine apart from testing for diabetes, which I’m waiting for the results on. I noticed a weird smell coming from myself and I knew it wasn’t a hygiene issue. While on the way home from the appointment I realized my belly button was itchy so I took a look at it and it was pretty bloody. I got home and cleaned it out. No blood since then, but there is discharge. Slightly yellow discharge with a funny odor. I started feeling uncomfortable in my stomach. Some tightness and very dull pain. Like I ate too much. I kept cleaning and taking it easy. Saturday rolls around and there’s still some discomfort, but it went away for the rest of the night. I wake up this morning, Sunday, and clean my belly button once more. I started noticing, as I was moving around, that it felt like the tightness and discomfort was moving up the right side of my body. Right up the right side. As if there is a small balloon in me. I also felt like I had to use the bathroom. I couldn’t the first time, but I just did. It feels like I’m constipated. I also feel very shaky. I know this is a lot of information and I’ve made an appointment with my gyno. I would just like some feedback as soon WS possible, while I wait for my appointment, without someone telling me to go to the doctor. I know someone can share some knowledge about this even if it is a guess. Thank you.
