I went to my obstetrician yesterday and she told me to not worry about the cyst and the main concern now is the possible retained products from my miscarriage 5 weeks ago. I guess it is not that big of a deal (hopefully). She actually did not even discuss about the cyst other than "don't worry about the cyst"...

So I guess her suggestion is watchful waiting...
Now I am just being paranoid everytime I sneeze because I am freaked out that it might rupture my cyst.
I am not and I was not on any fertility drugs or treatment. I did have a miscarriage 5 weeks ago though, and the cyst appeared 3 weeks after my miscarriage. Maybe the cyst is a result of not ovulating after my miscarriage or something...I don't know.
