symptom spotting 🙄

I'm trying so hard not to symptom spot. I'm 9dpo and I'm starting to get weird things that I've never experienced before. For the past three or four nights I've felt so feverish I've taken my temperature, no fever. I feel like I just ran a marathon, every day. At 6dpo I had a terrible headache for most of the day, which worsened after a horrible cramp in my right side. At 7dpo and 8dpo I had some (tmi) almost snotty cm, that I've never had before. I've been burping a lot since around 4dpo and I literally never burp. My SO even commented on this, lol. I feel so out of the ordinary. It's like I feel sick every single night around the same time, too. BFN with my FMU today. It could just be my anxiety. I dunno, just needed to get this off my chest. Does this sound promising or am I freaking out over nothing? What have you ladies been experiencing? Ever had all these symptoms and been pregnant, or not?
