No way to know for sure until you taste it or until it finishes (FG).
However, you may have made the wort more fermentable and thus have a lower FG. Not much you can do at this point, but I wouldn't worry about it.
You could always sanitize and add carapils/carafoam to add body. I've never done this, but an employee at the LHBS mentioned that he has done this with success.
