Hi, end of Jan 2014 I had done a USG (inside vagina) for delayed periods, which gave results of a positive pregnancy and a also a cyst of 17 mm X 18 mm size in my right ovary, i had gone for medication to clear the issue and repeated another USG of abdomen in Feb which was a normal study. Now for the last 1 month i am suffering from back pain and abdominal pain and severe gastric complaints, I checked up with my gynec who gave a through physical chek up and gave me a normal study. I am worried if the cyst has grown and is creating problems, plz help.
