Ovarian cyst..scared

My husband and I have been trying to get pregnant for sometime now and have had no success.  We are not giving up.  Last week I started having some weird back pains, which was originally diagnosed as kidney stones.  The pain did not go away so I went to th doctors.  After having a CT Scan, my doctor found a 9.7cm cyst on my left ovary. Now that a pelvic ultrasound has been done, surgery is scheduled for 3/20 to remove the cyst.  My doctor believes that at this time is there is no cancer. But still very scared.  My biggest dream is to be a mother.
