First off, I just want to say that there is absolutely no reason to be ashamed of being nude in front of your husband. You gave him one of the bests gifts in the world.
That being said, I would say continue doing what you are doing. If you aren't already working out, I would add that in. 100 calorie packs aren't the greatest things in the world, but compared to what most people eat, they are much more ideal.
You sound like you are eating the right things. Are you being 100% honest with yourself about what you are eating? I just read an article that people often underestimate the amount of calories/fat they are eating by close to 50%. I reccomend logging 100% of your calories for 2 weeks in order to get a better idea of what is going into your body. Good luck!
