having a lot of gas post-fast

I am having a lot of gas after coming off of a 21 day fast. This is day 4 post fast. I have followed the directions completely and other than this everything has gone well. I am drinking lots of water too. Today I added an all fruit smoothy in the morning and ate the soup for lunch and dinner. The gas started yesterday. I also have not had a b.m., but I haven't really eaten a lot, it still doesn't take much to fill me up at this point.

Is this normal?
