Hormone help

Hello everyone! I hope all is well. So my doctor and I are still trying to hone in on what is wrong. I was feeling better for a little bit but feel prettty bad today. I want to start looking deeper at my hormone levels. I heard that saliva tests are pretty accurate. Does anyone have any suggestions on how to go about this? Also, does anyone have suggestions on how to interpret the information after hormones have been tested? Any advice or hope would be great.

Also I am 23 so I still get periods and all that
