I'm happy to hear all of your labs came back negative, Sabacatheals. However, I can understand that it's frustrating to not find the answers you were looking for. I hope that the appointment with the rheumatologist in a few months will help you find some clarity on the situation. Fibromyalgia and lupus share similar symptoms, and some people are diagnosed with both fibromyalgia and lupus. Only a trained medical professional will be able to help you differentiate your symptoms and help you determine what's going on. 
And thank you for posting 😀. So glad that you found our community. Please do keep us in the loop on how you're doing as you seek more clarity on the situation. Best, - Cody (Team Member)
