I second what everyone else said -- I wouldn't worry, it sounds like you are eating a very healthy diet. Just remember to average your weight loss out over the month and over three months. You may lose very rapidly for a while -- 20 pounds or so in a month -- and then nothing for another month or six weeks. Your average rate of loss per month would still be high if that happened. It's almost inevitable that after a whoosh you will go through a period where you don't lose for a while; your body needs to adjust to the new weight.
