What am I doing wrong here?

I had my 5th fill yesterday. I got on the scale and have only lost 3 pounds in 5 weeks. WTH!?!?! I almost started crying from frustration. I don't know what I am doing wrong that I am not losing the weight. I know that 67 pounds in 6 months is great but I thought I would lose more. I am eating right and exercising. I don't know if I need to eat differently or change up my exercise routine. But I am having a hard time doing what excersie I am doing because I am in pain most of the time from my Lupus. Maybe I am just being too hard on myself. I am still losing and I need to remember that this is a life long process not an overnight miracle. Things will all work out how they are supposed to. If anyone has ideas on what I can do to bump up the weight loss let me know.
