Have you checked the gravity? The gravity (brix) is very low in blueberry. For any alcohol and flavor you need a gravity of 1.080. Yes, you will need to add sugar. Do not try to make wine withought a hydrometer.

I also agree that you should have a hydrometer to know what you are doing especially with making fruit wines where unlike grapes they almost always require sugar addition to get to an exceptable sugar level.
