Several women here have had this done (and were pregnant too). I hope that they come along and post soon.

hey mommatomaddie, yes, i have had a cyst drained before, they 20 cc's out of it. it's not the most pleasent experience in the world but yes it can be done. with me, they went through vaginally and i was able to see everything they were doing. with you being pregnant this is the safest way to go instead of going through surgery. good luck and God Bless you and your baby
