Hi,
Here is how I look at it....
A cyst with your medical history is likely to be a functional ovarian cyst. However the exact diagnosis can be confirmed only on aspiration/ removal.
I believe that if you have worsening symptoms then an early removal maybe needed since a symptomatic cyst becomes an indication for removal. The amount if discomfort that you are describing is probably acceptable since you do not have significant issues at rest. Curtailing the exercises and more walking as you have done seems appropriate at the present moment.
I would wait for the CA 125 results, and the next ultrasound before taking the next step. The next step could be a cyst aspiration, OR even a removal depending on these reports. No other tests maybe needed before this,
I can understand the frustration due to a lack of definitive diagnosis, but this is a common situation, and your present management seems appropriate and logical.
All the best,
