Ovarian Cyst, anyone have some advice

Options
Ok, so I went to the Dr. regarding my cyst today. It did shrink by one inch, so it is down to around 4" in diameter. That's good news :) My choices were a) wait it out and hope it gets better b) lapriscopic surgery to drain the cyst and take a look around to see why it may be there. Wow, great options...Anyone else go through this?

I do have PCOS, but that is mostly unrelated to this new one. I am hypothyroid, which can increase risks of getting a cysts and I have a Mirena.
