It took 46 days but I'll take it. I am so relieved.
About a week ago I stopped being able to feel the cyst so I was hoping that meant it was going away. Yesterday I started spotting and today full flow. I feel a great relief - the cyst and delay of my cycle was really causing a lot of stress to me. I didn't know what to expect and I was carrying all of the tension in my back and neck.
Phew. Now, just wait a month and then back to the RE.
